Carving blade HSS large

HSS blade for carving knives, with handle, forged

Cutting length 80 mm, total length with handle 210 mm

In contrast to the other tools from the company Pfeil, these carving blades only have a basic grind.

Information on the new HSS carving blades:
The high-speed steel HSS (High Speed Steel) has a high proportion of molybdenum (5%) and tungsten (6%) compared to conventional tool steel. The alloy components molybdenum and tungsten ensure, through the formation of carbide with carbon in the structure, that the steel has a high tempering resistance and hot hardness, high wear resistance and cutting edge retention as well as increased toughness with the same hardness compared to tool steel.
The HSS used for the carving blades is hardened to 62 HRC (Rockwell hardness). The big advantage of the HSS is the longer service life. The knife stays sharp longer, it doesn't have to be sharpened as often.
However, regrinding is more difficult - precisely because of the hardness. Soft and porous special disks (high-grade corundum or borazon) are required for regrinding.
The HSS is also less tough - i.e. more brittle. The conventional carving knives (tool steel) can be "bent" a little in the blade with an optimal cutting edge life; they give in to pressure. Carving knives made of HSS cannot be bent, so they are not very "elastic". You're more likely to break.
Both types of steel are high-alloyed but not rustproof. Rust-resistant knife blades do not keep the cutting edge as long as the two qualities mentioned - HSS and high-alloy tool steel.
