BENCHMARK KNIVES D2 CRACK

Conversely a blade can be extremely tough and able to bend but will struggle to hold it’s edge.

BENCHMARK KNIVES D2 CRACK

Some blades can be made to be exceptionally hard but will chip or crack if you drop them onto a hard surface. The biggest trade off is balancing strength or hardness with toughness. Unfortunately the “best knife steel” is not simply a case of maximizing each of the properties above…. >Here’s a knife with the best performing steel for edge retention< For me, edge retention is a combination of wear resistance and an edge that resists deformation. It’s what everyone talks about these days but unfortunately the measurement of edge retention lacks any defined set of standards and so much of the data is subjective. Edge RetentionĮdge Retention represents how long the blade will retain its sharpness when subject to periods of use. Note that a high resistance to corrosion does involve a sacrifice in the overall edge performance. Corrosion ResistanceĬorrosion resistance is the ability to resist corrosion such as rust caused by external elements like humidity, moisture and salt. However, carbides can become brittle and crack, thus decreasing toughness. In steels of equal hardness, the steel with larger carbides (think microscopic, hard, wear resistant particles) will typically resist wear better. Wear resistance generally correlates with the steel’s hardness but is also heavily influenced by the specific chemistry of the steel. Adhesive wear occurs when debris is dislodged from one surface and attaches to the other. Abrasive wear occurs when harder particles pass over a softer surface. Wear resistance is the steel’s ability to withstand damage from both abrasive and adhesive wear. In general, the harder the steel the less tough it’s likely to be. Charpy, Izod) thus it’s less standardized than hardness when it comes to knives. There are a number of different ways to measure toughness (i.e. Chipping is a knife’s worst enemy and never easy to fix. Toughness is the ability to resist damage like cracks or chips when subject to impact or “sudden loads”. Hardness in knife steels is directly correlated to strength and is generally measured using the Rockwell C scale (aka “HRC”). Hardness is the ability to resist deforming when subject to stress and applied forces. Ultimately, the different types of steel used in knife blades each exhibit varying degrees of these five key properties: Hardness
