Cutting ability and edge holding performance of Talonite vs VG-10 at a medium finish


Introduction

This is a followup to some work done with a Talonite blade with a high polish [ref ]. A similar method was used, 1/8" cardboard as blunting stock, and measuring sharpness by push cutting thread and slicing rolls of denim. The edge was applied to both blades by a fine DMT twelve inch rod. The Talonite blade was compared to a VG-10 F1 from Fällkniven. The F1 has a cutting length of ten centimeters, the Talonite blade is slightly shorter at nine centimeters. Both have similar edge profiles with the bevels at about 20 degrees.

The performance

The cardboard cutting was stopped after cutting 2000 centimeters as there was none left. However both blades performance had degraded seriously by this point anyway. String cutting :

Edge deformation shown by force needed to cut string
Blade Initial Round 1 Round 2
VG-10 292 +/- 16 462 +/- 40 510 +/- 14
Talonite 294 +/- 14 474 +/- 18 574 +/- 42

and denim :

Loss of edge bite shown by number of strokes needed to cut a roll of denim
Blade Initial Round 1 Round 2
VG-10 2.4 +/- 0.1 3.4 +/- 0.1 4.2 +/- 0.2
Talonite 2.5 +/- 0.1 3.3 +/- 0.2 4.0 +/- 0.2

What was learned

In short, at a medium finish the Talonite MEUK and the VG-10 F1 behave almost identially with respect to initial sharpness and edge holding ability.

UPDATE : as noted in the comparison vs CPM-10V at a high polish, methods have been significantly updated in the years in which this review was written [ref ].
