Kershaw9" Ultra-Tek Sharpener, 600-Grit Diamond-Coated Oval Shaft, Portable Blade Sharpener Tool for Knife

I should have known being made by kershaw it would be quality! What a phenomenal sharpner! Absolutely worth every penny! It's very portable. Easily used and stored. It only takes 3 swipes on each side to sharpen my santoku. Great sharpener!

For the ease of carrying alone, this sharpener would get 5 stars. It is super compact and is very durable. It has been dropped multiple times, is used daily on a D2 Benchmade and has survived saltwater exposure. This is a great daily use sharpener for touch ups. Highly recommend

Wow-wie! Took this bad boy to the field and harvested an animal. Kept my knife SHARP. Didn't even need to pull out a bone saw I could get through joints super easy. Couple quick wraps to remove the beveal, wrap against my honing leather if needed... Sheeeesh!10/10 would buy again in a new born Heart Beat.

I’ve been using the Kershaw Ultra-Tek Blade Sharpener for a few months now, and I’m really impressed with its performance. The unique design, with the diamond-coated shaft stored inside the handle, is perfect for my deer hunting trips. It’s compact enough to fit in my pocket or day pack, making it super convenient to carry around.The sharpener does an excellent job of keeping my Kershaw knife razor sharp. I found it especially useful for putting the finishing touches on an already good edge. Just remember, it won't replace a good whetstone if your knife gets too dull. Overall, it exceeded my expectations, and I’d definitely recommend it to other knife enthusiasts.

I have several sharpening methods, and own two other diamond stone gadgets.This is a very clever system, and frankly had it not been for a respected guide and the Kershaw brand, I'd have been too skeptical to buy this.But I wanted something for remote field work, and my diamonds stones are just too big, so I decided to try it.Wow. It does a brillaint job of sharpening. I've tried on on over a dozen different knives now and they all took an edge with little fuss.Perhaps it's the oval shape of the stone, or mayb it's becuase I'm usded to using a steel, but for whatever reason, I seem to get a respectable edge with out a great deal of discipline in the stone-to-blade angle.Obviously you can'it just ignore the angle, but it's easy to be in the "ok zone".With just a little care, I can get to "scary sharp" and without unpacking the stones, sharpening fluids...So, this is easy, cheap, and excellent. Almost too good to be true, but it is true... for me at least

Really does aGood job of sharpening

I've purchased many knife sharpeners, and this one is the best. Easy to use and it doesn't take forever to get a very sharp knife.

I have made knives and know how to holds an angle. If other do not hold the right angle this would not be the right sharpener for them.
