What does zero grind refer to if I may ask... like a chisel grind...

Hey Buddy,
Thanks for your interest in my work!
The vast majority of knives currently produced worldwide have bevels which are ground to a specified depth resulting in an edge thickness somewhere between .005" and 040". These knives are later sharpened at a different angle which results in a secondary bevel.
In other words when these knives come off the grinder they are not sharp, they could give you a good bruise but thats about it. They still require sharpening before being completed.
Zero ground knives have primary bevels that are ground all the way to sharp.
Instead of grinding to a certain depth and then later sharpening, the zero ground blade is taken all the way to sharp while grinding the primary bevel.
When the knife leaves the grinder there is a visible burr along the cutting edge and unlike the traditional knife with a secondary bevel this thing will cut your finger completely off. They will send you to the emergency room real quick.
I only build about 10% of my knives with a Zero Grind. They are difficult to work with during subsequent handle installation procedures as well as sheath fitting and just very, very dangerous in general.
The other 90% of my knives are sharpened Last. after all handle and sheath work has been completed.
Here are a few pictures illustrating the zero and secondary bevel edge configurations.
If you can see where the blade was "sharpened" its not a zero grind.
Thanks Guys!!
