Can I sharpen thicker hunting knives with the Knife & Tool Sharpener?

YES! Due to the thickness of the blade, the bevel may not appear like the factory bevel.

Can thicker hunting knives be sharpened at a 40 degree angle?

Yes! You will want to start out at the 50 to see if that works as well. Sharpening a thicker knife at 40 degrees will create a higher bevel then normal but is perfectly fine.

How long do the belts last on the Knife & Tool Sharpener?

The provided belts will sharpen about 100 knives. Note: Shaping knives or changing the angles will consume the belts much faster (more MTO). Other grinding and tool sharpening will play a factor in the belts longevity.

Is the Knife and Tool Sharpener strong enough to grind a new bevel onto knives?

Yes!'

What size are the belts on the Knife & Tool Sharpener?

They are 1/2 x 12

I live outside North America - can I use my Work Sharp Sharpener with an adapter?

Drill Doctor, Work Sharp, & Darex Sharpeners sold in the United States and Canada are designed and manufactured for 115V 60 Hz power supplies only. We assemble and ship product for a specific region's power needs to many distributors around the world. We want to make sure you have the correct product to safely and effectively sharpen your tools.

Using a 115V machine in a location that uses 230V power sources not only voids your warranty, but also increases the chance of failure and reduces the life and performance of your tool. We want you to purchase the proper tool so you can experience the optimal performance and life of our tools.

Why is this important?

    First some clarification:
  • A Transformer reduces or increases AC voltage
  • A Converter converts current from AC to DC
  • An Inverter converts current from DC to AC

Using a simple plug adapter and no other transformation or conversion from 230v to 115v leaves the unit running on twice the rated voltage—the motor runs very hot, very fast and for a very short time before it destroys itself. A plug adapter allows the US-plug to fit into your receptacle, but doesn’t impact the power provided to the unit.

Our products do not have a ‘smart cable’ like you would find on a laptop that has a built in power supply to take input current/voltage and transform it to lower voltage. That Power Supply converts from AC to DC current at the low voltage (1-24vDC) input needed for a laptop battery or similar device.

A transformer (not a complete power supply), plugged into single phase 230v, can drop the voltage to the 115v range, but doesn’t account for the difference from US frequency at 60 Hz and Internationally at 50 Hz and may not regulate the voltage or provide sufficient amperage well depending on the quality of the device. Running on 50 Hz puts a greater strain on the motor, so while the correct voltage may be supplied to the unit, the frequency isn’t correct to get full performance (reduced power = lower efficiency = extra heat = destroyed unit). The voltage may also not be precise, out of a transformer and the 115v motors are designed to run in a specific range. High or low voltage will likely cause failures.

Forgive the long winded explanation but we want you to have a proper functioning tool that you are satisfied with now and long into the future.

The glass plate seems to wobble and the retaining bolt seems very eccentric.

The knob is centered by only it’s threads which is why you see “knob wobble".It's function is to hold the wheel down, the output shaft is what positions the wheel to center. The wheel can also appear to be eccentric due to the placement of the abrasive on the wheel. Even if the glass wheel is slightly eccentric it will not affect your sharpening geometry.

Can the WS3000 sharpen dog/flat hair clipper blades?

Yes, using the very fine grit (P1000 and 3600 micro mesh) take the clipper apart, place the flat side against the wheel on the fine abrasive (P1000). Turn the machine on and let it sit for only a few seconds. Then, using the finer abrasive(3600), repeat.

Can the WS3000 sharpen knives?

Yes, you can purchase the WS3000 Belt Sharpening Attachment. This new accessory sharpens a wide range of angles (10° - 35°) on knives, scissors and many other woodworking cutting tools such as marking knives and carving tools. This accessory is available on our website now.

Do you need to use anything to maintain this machine?

The machine should only require a regular cleaning and dry storage. We prefer using a stiff brush on a shop vac to clean the wheels and machine. Make sure the machine and grinding wastes have completely cooled before using a vacuum. The media will last a long time if cleaned regularly. (Avoid getting the wheels too hot in storage or the abrasive discs will be difficult to remove.)

I cannot get a squared chisel. How do I skew in my machine?

Using the skew adjustment lever will determine which part of the port it will raise. If the chisel is coming out positive (left edge high) you will need to raise the skew cam. If it is coming out negative (right edge high) you will need to lower the skew cam. Using to much load force in the sharpening port can also create skew. We recommend light pressure in the sharpening port. Let the tool do the work!

I use many different router bits and find they are difficult to sharpen by hand ,will the WS3000 help me sharpen router bits?

No, the WS3000 was not designed for router bit sharpening.

Why is the WS3000 sharpening port only 2' wide?

If the sharpening port was any wider it would produce an irregular grinding pattern that is difficult to sharpen to a keen edge; since the abrasive would then be grinding into the edge as opposed to away from it. This is where the Wide Blade Attachment should be considered.

Can the glass wheel for the WS3000 be used for the WS2000?

No,the safety standards established for use of this product by UL and ETL do not permit using the glass wheel on a tool that has an rpm of 1750. If the wheel fractures at that speed, it will eject glass fragments that can cause injury.

Can the WS2000 sharpen knives?

Yes, we offer an optional attachment for sharpening knives: Part Number WSSA0002009. The Work Sharp 2000 will not sharpen knives without this attachment due to the single direction of the wheel spin.

Do you need to use anything to maintain upkeep on his machine?

The machine should only require a regular cleaning and dry storage. We prefer using a stiff brush on a shop vac to clean the wheels and machine. Make sure the machine and grinding wastes have completely cooled before using a vacuum. The abrasives will last a long time if cleaned regularly. (Avoid getting the wheels too hot in storage or the abrasive discs will be difficult to remove).

I am missing parts from the box.

Please contact Customer Service. 800-597-6170

I have the WS2000, on page 10 of the user guide it shows that I should have a solid wheel.

The picture indicates the slotted wheel will accommodate the SOLID abrasive.

I own a WS2000, is there an accessory available for sharpening 6" or 12" jointer/ planer knives?

No,they are too long (11" - 13") and spin on a power tool at high speeds - therefore ANY imbalance or variance in MTO during sharpening will create a vibration that could be very dangerous.

The spring on my WS2000 is weak,loose,missing or stretched .

Please call DAREX for instuctions and replacment parts.

Can I use an inverter with the WSKTS-KO?

We've found using a quality inverter with a true continuous output above 400-watts works for most light sharpening and honing.

What is the range of the variable speed motor on the WSKTS-KO?

The speed is measured in surface feet per minute (SFM), which is the length of abrasive belt that passes over the blade in one minute. The machine uses a variable speed control motor that ranges from 1200 SFM to 2800 SFM.

Why shouldn't I lock the power button when I'm sharpening knives?

With the motor running full time, the abrasive belt is grinding the heal of the blade as you are lowering it into the angle guide. This additional exposure to the abrasive can grind the heal more than the rest of the blade. Over time, the extra exposure to the abrasive will create an unintended ‘recurve’.

Place, Power-on & Pull. is the best method when using our sharpener to maintain factory blade profiles.

Tell me more about different finished edge types?

  • A toothy edge is a great general purpose kitchen knife edge for cutting vegetables, and great for pocket knives used for cutting rope, cardboard, and other regular duty tasks.
  • Shaving sharp is best in the kitchen for cutting meat and fish, or if your pocket knife sees light or delicate cutting tasks.
  • Shiny sharp is fun to achieve, is super sharp, but does not tolerate abuse and will lose its cutting efficiency quicker.
Multiple edge finishes can be applied to a single blade, just as some blades have partial serrations.

How do I sharpen ceramic knives?

To sharpen ceramic, use the optional diamond belts and use the same techniques as sharpening steel blades. Ceramic knives will not create a burr to let you know when to switch sides, so be sure to use the same number of strokes for each side to ensure a consistent bevel.

NOTE: The diamond belts were developed specifically for repairing sharpening ceramic blades. Do NOT use the diamond belts to sharpen metallic knives, as the metal will clog the belts and render them useless.

How do I sharpen my Tanto knives?

  • Tanto blades require 100% of your attention.
  • Sharpen each edge as an individual blade. Part 1 is from the heal of the main cutting edge to the transition point. Part 2 is from tip to the transition point of cutting edge. Do not sharpen past the edge transition angle or you risk rounding it off. Again, Tanto blades require 100% of your attention to avoid rounding off the transitioning angle.
You can also freehand your Tanto on your Ken Onion Edition without the sharpening guide or use the Blade Grinding Attachment. Freehand sharpening takes much more practice than sharpening with guides and as always, practice with "junk" knives first to develop your skills.

Can I bench mount my Ken Onion?

Yes, you can. There are two 1/4" coarse threaded holes (20 threads per inch) on the bottom of the machine. (Note: Some older machines may have only one threaded hole.)

How do I keep my blade face scratch-free?

  • Stay clean! Keep the guide and blade clean after using each grit. An old paint brush works great for this.
  • Use little to no pressure against the outside edge (against the angle guide). Use it to set the angle, then ‘hover’ the blade through at the set angle.
  • The best protection from loose grit is to cover the face of your blades with tape that is easily removable, exposing just the bevel while sharpening.

What is the difference between the Original Knife & Tool Sharpener and the Ken Onion Edition?

    The Ken Onion Edition features 3 key upgrades:
  • Adjustable angle guides from 15° to 30° (vs. fixed guides of 20° and 25°)
  • ¾” x 12” belts, including many optional specialty grits (vs. ½” x 12” belts)
  • Variable-speed, heavy duty motor (vs. 2-speed (full-time and intermittent), fixed RPM motor)

What is the benefit of Pivot Response?

Manual sharpening is difficult to do and requires a lot of practice and patience to be proficient on a flat stone. The biggest challenges are maintaining the sharpening angle and sharpening the entire length of the blade consistently (the belly or curve of the knife is a challenge). Other guided systems use elaborate clamps, jigs and fixtures to solve these problems. The GSS solves these problems with easy to install and use angle guides, and by allowing the abrasive surface to pivot and follow the curve of the blade as you sharpen. So wether sharpening straight or curved blades, only one technique is required (holding the blade perpendicular to the abrasive). The Pivot Response will respond to the blade profile and create a very consistent edge along the entire length of the blade.

Which edge is better, convex or flat grind?

There isn't a single edge profile that is best for everything. Every type of edge grind has its advantages and disadvantages - depending on the cutting task at hand. No matter the grind, sharp is all that really matters.

Why did you choose the angles you did?

The most common edge angles are 17° and 20° - though factory edge angles vary over a much broader range. Kitchen and filet knives perform well with a 17° grind for most common tasks; while most outdoor/hunting/pocket knives perform well with a 20° grind. As higher quality blade steel has become more affordable, knife types that had typically been ground to a 25° angle are now being ground at the factory with a 20°angle due to the superior edge qualities of the higher quality steel.

Why is the honing and stropping angle 5° greater than the sharpening angle?

This creates what is called a micro-bevel and is a common knife sharpening technique. By increasing the angle during honing and stropping, less material needs removing to finish the blade, speeding up the honing and stropping process. The micro-bevel is also quicker to tune-up between sharpenings.

How do I know if I've sharpened long enough?

Feel for a burr. That is your indicator that you have removed enough material. Continue feeling for a burr as you progress through the coarse 320 and fine 600 grits. The burr will get smaller and smaller as you progress through each grit. An edge with no burr is the goal. Once finished on the ceramic rod, there should be no burr remaining.

I have a long blade, how can I sharpen it?

You can work in sections on long blades. There will be overlap in the center but that is okay. Use a few full, light pressure swipes to finish.

How often should I condition my leather?

Whenever it looks dry. The petroleum jelly opens the leather's pores and allows the honing compound to be absorbed. Your ultimate goal is for your leather to acquire an almost black glassy appearance with age and use.
