About Convex

There is nothing New about Convex Grinds or Convex Edges.

All Knives-Swords-Axes and Cutting Tools have been Convex Ground and
Sharpened from the Bronze Age to about 1900. The Advent of Automated
Grinding during the Industrial Revolution saw the first V-Bevel methods of
Sharpening knives. This was necessary because there are no machines--even
today--that can do a proper Convex Grind or Convex Edge.

Convex Grinds and Edges are all Hand Done.

The Advantage of the Convex Edge is that it supports the Carbides on the
Cutting Edge by an almost 400% advantage to the -now common- V Bevel.

Convex Edges hold thier level of sharpness far longer than a V bevel and are
4 times tougher. They are also deceptivly sharp.

The Thick Edge Spine holds the carbides on the edge to such a longer degree
that the knife stays sharper far longer and will still cut long after a
conventional V bevel has gone stone dull.

Convex Edges are also the Easiest to Maintain and restore.

A quick strop and they are right back to Razor Sharpness.

All of the Classic Series of Blackjack Knives are Hand Convex and Hand
Sharpened in the Traditional Manner to give you the Ultimate in cutting
performance without compromising strength and toughness.
