Diamond Knife Sharpener

Item: # 09841

Even with high quality steel and excellent craftsmanship, every knife must ultimately be sharpened. This triple diamond-plated design is durable and sharpens both serrated and fine edge blades.

Very dissatisfied... I just got home and tried it and the diamond grit started flaking off. I bought it at a Sports Authority that is closing so I can't even get a refund or exchange. I only paid $11.69+ tax but it being Gerber I expected a quality item... I probably would've faired better buying cheap made in China knock offs....

bought this 2 days ago and sharpened two knives. In the middle of the flat part the diamond material bubbled up and flaked off

I used this prodct once and the coating came off I can't believe it is on the shelves. Now I have to waste my time taking it back.

NOT happy at all! I expected better from Gerber! I used it one time and the surface is now smooth in spots! At this rate, it might last through about 3 sharpening's. What a waste of $10!

I sharpened 4 knives with this sharpener. I used the flat side exclusively. After those four knives were complete, the tool was worn out. All of the abrasive material had disappeared. I couldn't believe it. Very disappointed.
I'd like another one sent to me. I purchased mine at Cabelas in Minnesota.
Thank you.

Piece of junk. Diamond coating flaked off the first time I used it. Wish I saved the receipt and packaging. If there really is a "lifetime warranty", e-mail me how I take advantage of it. Sending it back would likely cost me more than I paid for it. Major disappointment. and sad commentary on Gerber product Quality.

Got this sharpener in the kit with hatchet knife and saw. I sharpened the hatchet once and the flat part is now smooth. Figured It would last long enough that i could sharpen all 3 at least a few times.

Have used this sharpener in the field for 6-7 years. Recently lost mine on an archery hunt and replaced as soon as we got home. Essential gear

This is such an awesome sharpener. Its incredibly light and works extremely well. My Dad was so impressed he's going to buy himself one. I highly recommend this!

  • |BY: , Best knife sharpener ever

I bought one of these a couple of years ago and so far its been the best portable knife sharpener I've ever had. It takes the place of most stones, its light and small.
