6" Vegetable Knife $150. There are five available in this sale. You will receive a different knife than the one in the picture.
Please read the description and understand this knife before buying one. It is not a general purpose knife for everyone.
This is an affordable, no frills, single bevel vegetable knife pattern designed for food release on sticky foods like potatoes and carrots etc. It is intended to leave a neat manageable stack of food. It can also be used to slice fish and other delicate foods that need an extremely sharp fine edge.
The "grind" is scalloped and is a tall thin parabola that is a conventional flat grind at the bottom that develops increasing curvature as it approaches the top of the grind. This kicks food off and reduces the adhesion that causes slices of food to march up and go over the top of the blade. See video. This is a single bevel hollow ground kitchen knife whose geometry is similar to a one sided straight razor. The geometry is more extreme at the heel of the blade where you'll do most of your chopping and more conventional towards the tip for regular slicing with the point.
The final edge is applied by hand on oil stones. Being single bevel, the flat side is honed flat, or nearly flat, to the stone. I had to choose between keeping these pretty and getting them sharp and I chose to get them sharp. So these are new knives and the flat side bevel will have some minor scuffs from sharpening.
It is for right handed use. If you're left handed you will be better served with something else.
The steel is AEB-L at HRC 61-62. This is a clean, fine grained, stainless steel with a relatively low chromium content and no carbide so it behaves very much like a simple carbon steel. These went into full cryo as part of the quench which, in this steel, eliminates structures that cause issues with fine edge stability in stainless.
The edge is thin enough to be flexed on your thumb nail. It should not be used on bone or against glass or ceramic cutting boards.
The handle is two part construction hidden tang. In addition to the visible cutlery rivets there are internal "epoxy rivets" and a hidden metal pin. The blade/ferrule/handle transition is sealed with Acraglas resin. The ferrule is internally knurled and bonded to the G10 scales, it will not come loose over time.
There is no maker's mark. I normally mill my signature into the blade, but I left it off for food hygiene because it's relatively deep.
The knife is made of NSF 61 compliant materials and is suitable for use in a commercial kitchen. And though I don't recommend it, the materials and construction will survive a trip though the dishwasher.
The knife balances on the ferrule.
Vegetable Knife specs:
1/8" AEB-L tested HRC 61-62
Total length 11"
Blade length 6"
Weight 6.7 oz
G10 handle
304 stainless ferrule

These are field grade, as machined and stonewashed with a medium grit grind applied to the left side and a semi-polished edge. They are $150 plus $5 shipping in the USA.
These knives are unusual because they are machined. I do this in my shop on industrial CNC machine tools. A WIP thread documenting my technique can be found here: http://www.bladeforums.com/forums/sh...ad.php/1048443
I take paypal, cash, check or MO.
First come, first serve, posts in this thread
Thanks for looking,
