Drive Review: Industry Standard for Knife Grinders


Knife making is the process of manufacturing a knife by a combination of processes.  Professional knife makers shape pieces of steel into blades as part of the knife making process.  They typically use a large industrial belt sander or grinder, made specifically for knife making. The belt sander or grinder is used to remove the excess metal from the blade and then hone it into the shape they need.  The knife making machine needs to run quickly when the knife maker is first starting on the blade, so they can remove the maximum amount of material.  It then needs to run more slowly when putting on a fine finish.  In addition to variable speed, the machine needs to provide controlled starting and fast stopping of the belt or grinder wheels.


KBAC Hybrid Drive is the solution to provide variable speed control
of 2 HP or 3 HP motors commonly used on knife grinders.


The KBAC Hybrid Drive has:

  • Controlled acceleration
  • Fast deceleration of the high inertia load
  • Smooth slow speed operation

Producing a reliable finishing of high quality knives
