Casstrom Woodsman Knife Roger Harrington Design Bog Oak With Firesteel
A new bushcraft knife from Casstrom.
A classic wilderness knife designed by custom knife maker Roger Harrington, from England.
Proper full-tang knife with a blade measuring approx. 9cm long , a straight and fairly round handle made to suit both large and small hands. The leather cord for the handle and a strong deep pocket leather sheath is included and a matching fire striker
The blade is made of around 4mm thick Bohler K720 high carbon tool steel to make the blade extremely durable for heavy use such as log-splitting, or so-called "batoning" without making the knife to heavy or uncomfortable to carry.
The knife has a Scandinavian grind to make it very robust at the same time easy to carve wood with and easy to sharpen on a small flat whetstone/sharpener in the forest. The knife is a really good all-round tool for field use.
About the steel : Bohler K720
Bohler Tool Steel K720 (O2) is a very tough and strong oil hardened high carbon tool steel. The focus of the steel is toughness and edge stability. The chemical composition allows it to be hardened to a high degree whilst maintaining ductility and toughness. This means the blade holds its edge for longer at the same time as it is resistant to chipping and cracking under heavy use. This steel also has a very fine structure making it easy to sharpen and achieve a razor sharp edge with. Whilst easy to sharpen, the low chromium content means it will tarnish if left wet and it must therefore be wiped after use and protected by oil or wax when put away for storage if you want to avoid tarnish building up.
Steel analysis: C. 0.9%, Si. 0.25%, Mn. 2.0%, Cr. 0.35% V. 0.1% (HRC 58-60)
