HRC of this blade is approx 65 and you will find this blade will hold its edge an amazingly long time.
Because HAP40 steel has a high tempering temperature (550°C), it will not temper even if the cutting edge is sharpened with a machine grinder.
This HAP40 steel plane delivers a sharp, durable cut and exceptional strength, handling everything from standard lumber to hard-to-cut woods and laminated timber.
Its most notable feature is its incredible durability (long-lasting sharpness) when working with both hardwoods and softwoods.
