Identifying Blade Types - Drill Master X2 User Manual

Identifying blade types:

• Double-bevel knife.
Bevels on both sides
of the blade.
• Single-bevel knife.
Large bevel on one
side and flat on the
other.
• Serrated
Series of scallops
down a portion or
full length of the
blade.
A. Tip: The end of the knife opposite the handle. Often used for
small or delicate work.
B. Heel: The portion of the blade closest to the handle. Often
used for chopping or heavier cutting duties.
C. Primary bevel: The main tapered side(s) of the blade from the
spine down to the edge. The blade may be tapered on one side
(single-bevel) or both sides (double-bevel).
D. Secondary bevel: The small bevel at the bottom of a primary
that forms the cutting edge.
E. Edge: The cutting portion of the knife which extends from the
heel to the tip. The edge may be a single edge (straight edge),
a wavy/toothed edge (serrated edge), or a combination of both
(combo edge).
F. Spine: The top un-sharpened portion of the blade which adds
weight and strength.
G. Bolster: The front portion of the handle where it transitions
from the handle to the blade. This area may include a lower finger
guard to help protect fingers from contacting the sharpened heel
of the blade.
