Types of tool wearpdf

Any recommendations for local knife makers for culinary knives? Need a new chefs knife at a point in life I can splurge a little. Bonus points if they do Damascus steel.

Tool wear and failure can occur through three modes: fracture, temperature failure, or gradual wear. Gradual wear is preferred as it leads to the longest tool life. Wear occurs primarily at the rake face (crater wear) and flank face (flank wear) through mechanisms such as abrasion, adhesion, diffusion, chemical reactions, and plastic deformation. Tool life is defined as the cutting time until a certain wear criteria is reached, such as 0.5mm flank wear. The Taylor tool life equation describes the relationship between cutting speed, tool life, and material properties.Read less
