Just took it out of the box and sharpened several knives. The Ken Onion work sharp did a great job, and appears very well made. With four belts the user's guide and the removable sharping guide (all things that can get lost in a garage), this should have come with a bag or case for money. If they can do it for $99.00 drill, it should be done for a $149.00 sharpener.

Awesome tool. Got it today and went to work sharpening everything that has an edge. Worked great on everything from my kitchen knives to my garden shears to my EDC knife. Razor sharp and polished edges look and work amazingly well. Finally, my kitchen knives cut like new again.

Just recieved my wskt ken onion edition, im blown away by the quality and ease of operation of this device. First let me say im a total novice at sharpening...spent much money of cheap systems and could never get a sharp edge. For the total amount I paid for ineffective systems I could have started out with the wskt system, not only saving money but time and frustration as well.
To practice I took out 3 of the dullest kitchen knives I could find..I followed the included directions and in virtually no time. .not only did I get a sharp edge..I got hair shaving edges on all 3 knives.
This is by far the best system imo on the market..I would encourage any knife enthusiast to buy this product

Another set of belts would have been nice at this price,
wore them down pretty good practicing.

The knife guide definitely needed to be a little wider,
a little more design work, could have made this part better.

The belt truing knob is all the way to one side for two belts,
and could have been easier to work.

Almost perfect…. Thanks Work Sharp.

I used to use a steel or a wet stone but since getting this tool I can make my knives scary sharp in a lot less time than it used to take. I would have given this item five stars but I will say that after sharpening about 15 different items the belts started looking like they would need to be replaced. I looked into the price and they are almost 20.00 bucks for a new set. There should be an extra set included with the unit. Another reason for the four star rating is the price which I think is a bit high for its capabilities

I purchased one at the Long Beach Sports Show on March 5, 2014 after Doug Holser's demonstration. I am a fisherman and need to skin and clean rockfish, so sharp knives are very important form me. Since I got it, I have sharpened about a dozen knives to razor sharpness with just a few minutes of work with each one. I really like the selection of belts and grit sizes and how easy it is to change belts. Its a clever and effective device and the price is very fair for this kind of quality.

I just purchased my Work Sharp Sharpener (KO edition) and spent the last hour or so learning how to use it. I use an Edge Pro Apex usually, but heard good things about this unit so I thought I'd try it. First of all, it is extremely easy to put belts on and off. It does take a bit of getting used to when sharpening an outdoor blade (pocket knife) without the guide rest. Feels a bit freehand, but puts an awesome edge on the blade. No mess to clean up and the unit is small (and quiet enough) to use in the living room. The unit feels solid and extremely well built (not heavy though). Over all, great feel.

Adjusting the angle is easy and predictable. I was able to quickly put a sharp edge on two knives I have. Kershaw Blur (S30V) and Cold Steel Hold Out III (Aus8A). Without going to the 6000 grit, I was able to get a good edge on both. cut paper, hair, etc. I then used the 6000 (purple) belt and it became scary bleeding sharp ;-). I can do this with the Apex, it just takes longer since it can get wet (water stones, etc).

Overall a worthy contender wrt sharp. It's just quicker.

Edge and belt stay cool (low speed), and feels good in your hand.

The WSKTS-KO is one "get-r-done" little piece of sharpening genius!! The motor is plenty strong enough for those who don't want to burn the temper out of an expensive knife, but get really aggrivated at "grinding away" w/ stones/ceramic and even diamond sharpening solutions for hours on end. Those still tools have their place in 99.9% of my work, but the WSKTS-KO kills all the "grunt work" beforehand.

The adjustable speeds feature is a Godsend. I can use the slowest SPM and finest grit belt, and pretty much WATCH the honing magic transpire, one or two passes at a time, check, and try again---something I wouldn't feel comfortable doing on an industrial grade machine. I have CP, so big buffing wheels and grinders make me a bit skiddish. The X4 ceramic belt puts that blinding "samuari flash" polish on my knives, and I don't have to whip out the strops and compounds, unless I want to do so. Ive been sharpening knives 35 yrs. now, I wish the WSKTS-KO had come along years ago. The WSKTS-KO is light enough to transport and move around easily. Belt changeups are a snap, and belts can be cleaned w/ normal abrasive belt cleaning "sticks", available almost anywhere. This is a great tool for veteran sharpeners, and for beginners who will pay heed to the instruction manual, and do some online research and practice.

Having grown up in the meat business, keeping a sharp knife has never been a problem. This sharpener however allows me to take the edge to the next level. My high end chef knives are now carrying a polished edge that leaves them extremely sharp. This sharpener will allow those that have struggled with stones and steels to have sharp knives. I've recommended this sharpener to several friends and family members to allow them to have sharp knives in their homes.

The price was a bit steep but I'm totally impressed with the speed and edge I put on any knife I put to it. If the apparent quality causes the unit to last a few years than the price will be worth it. I've had so many other sharpeners that turned out to be worthless and this one seems to be what I've been looking for a long time.

The blade guides need to be wider to help support the blade tip better.
It's a great idea just needs more thought
And where is the leather belts??

I just received the Ken Onion Work Sharp, I've found there is a learning curve to master this unit so I'm still practicing. The Ken Onion has upgraded features over the original Work Sharp Field Edition, a larger motor, wider belts(More Surface Area), variable speed,adjustable angle guide plus an edge guide. I'm extremely happy with this unit as with the original, now I have the option to take one in the field and have one at home. Thank you Darex and Ken Onion for helping the average guy with the opportunity to be functional with all of his cutting tools. Gary E Williams

3 months for this after seeing it reviewed on You Tube, glad the wait was over, I love it, does everything as advertised. I did have to re order some blade guide rollers, they get a small groove in them after a few knives, but no problem, the staff was and is always so helpful there. Great product. Way to go guys :)

I just bought this sharpener from Sportco in Fife Washington today. As soon as I got home I took it out of the box and sharpened my Kershaw Blur with a 20° angle. About five minutes after I started I had the blade sharp enough to shave the hairs off my arm! It was too easy! My other sharpener is made by Gatco and gets the job done, but not this well and not this easy. It makes sense, the Gatco uses solid blocks that do not conform to the shape of your blade. The work sharp uses flexible abrasive belts that conform to the unique shape of today's blades. My blur has the S30V blade. I like it,... I like it a lot.

The work Sharp knife sharpener system is the only other way to go other than a good stone, but much faster. I gave it a ultimate test of doing mom' knives at home, they were C.C. brand and dull very fast. After 2 passes on med. grit and 2 passes of fine gri, I was able to fillet the skin off a tomato! Forget any other style, This is all you need, have tried it on the mower deck and will get this year's deer camp knives as well. A 5 star product!!

I bought the original Work Sharp unit two years ago and was satisfied with it. It took a place beside my Edge Pro Apex and Wicked Edge sharpeners. Yes, I am a knife sharpening geek!

But then I saw the Ken Onion model of the Work Sharp. I bought it immediately. I think I am one of the first owners! It is amazing. With the precise angle control, the stronger motor, and the killer accessories, this sharpener has replaced all my sharpeners. I sold my other systems on eBay and now use the Ken Onion model Work Sharp exclusively. I can't wait to get the upgrade knife shaper on October 14th. I know this sounds like a commercial, but I can assure you I paid my own good money for this unit and I am 100% satisfied.

If you are into stones...that's great. But if you want to sharpen any knife razor sharp in less than 10 minutes, then this is the sharpener for you. To be honest, you could start a business using this sharpener! Have fun! JH
