Optimal Apex Radius (edge keenness)

No Comments Uncategorized

Optimal Apex Radius would be the thinnest which sustain for intended usage. It would be inefficient to use a jack hammer bit keennes as a tomato slicer, flip around is unsustainable to use a gyuto sub micron edge for jack hammering. Both too thick & too thin lead to bad […]

Test Thin Cross Section

No Comments Uncategorized

A thin wedge is useful for testing material strength and toughness. For given suite of tests, a subject cross section should intersect with failure threshold points. Intersected points are along the wedge face. This set of points move up/down inverse proportion to wedge angle of subject due volumetric strength/stiffness changes. […]

CWF HT Tempering

No Comments Uncategorized

I’ve been tested most of CWF HT-ed knives in untempered condition and at peak hardness. Weaknesses are highly amplified when blade at this state. For some steels, this condition is actually their optimal operating/usage state – ‘micro ripple, macro fracture’ edge. For most of other steels, this condition (very stiff […]

Minimizing Edge Damages

No Comments Uncategorized

Let’s define, a cutting-edge as a wedge 0.08″ tall from the edge. And geometry: 0.01″ thick, 30* inclusive bevel, 0.5um apex radius. When this edge subjected to damaging forces: Pressure/Compression => increase hardness to limit damaging depth. Lateral => increase strength and elasticity. In effective, broaden (broad & depth) affected […]
