A 25 mm (1 in) x 25 mm (1 in) triangle trimming head in high carbon steel, set in a hardwood handle. Sharper and longer lasting than stainless, and it needs drying.
PT440 is the 25 mm (1 in) x 25 mm (1 in) triangle in Kemper's PRO-LINE range. PRO-LINE tools use a select hardwood handle with a loop of knife-quality high carbon steel, heat treated and quenched in oil. Carbon steel takes a sharper edge than stainless and holds it longer, at the cost of needing to be dried after use. The 25 mm (1 in) head decides how much you take per pass and how tight a curve it will follow. Dry it after use - high carbon steel will rust if it is put away wet.
