Gatco 10006 Ultimate diamond hone sharpening system

This is personally the sharpener that I own and it got me into knife sharpening.

Since diamonds are the hardest substance in the world, they take to sharpening knives and tools like a duck takes to water!

Diamond’s abrasive qualities are phenomenal and they can make quick work out of the toughest sharpening jobs and they are long-lasting, granted they are used properly.

This means the use of light pressure during sharpening to prevent the breakage of diamond crystals from their matrix.

The Gatco 10006 Ultimate diamond hone sharpening system utilizes the GATCO exclusive knife clamp/angle guide to ensure the proper angle is maintained during sharpening.

The Reviews

The Gatco 10006 Ultimate diamond hone sharpening system reviews well with Amazon customers.

This is the sharpener that I own. My knives sharper than when I bought them.

I can agree that I actually got my knives sharper than when I bought them.

I am talking about some great Wusthof knives. The best is when I started buying used knives on eBay for a fraction of the original manufacturer’s cost and sharpened those knives up.

What a huge bargain for some very sharp knives.

Eric E. also said he like the Gatco System, “I love it. Hands down one of the best systems on the market. I bet I have sharpened 500 Blades on my set now with never a complaint once. Amazing design and quality. You just can’t go wrong…”

He went on to add “I suggest buying a Gatco 12001 Easy-Grip Clamp Mount to use with this Awesome Kit.”

Small Blades

The one downside that is common with clamp style sharpening devices is that they have a hard time holding small blades.

This is a pretty big impact if you plan on sharpening small pocket knives or many paring knives.

That said, you can get by if you don’t mind taking a little extra time on those small blades. I also found that if I sharpen a blade at 22º or greater then it was no problem to hold the smallest paring knife that I own.

The fact is that most of the clamp style sharpening systems are designed for medium to large-sized knives and can accommodate knives outside that range but it often is not ideal.

GATCO might be a shortened version of their name Great American Tool Company but, one thing that GATCO is not short on is value and quality.
