Our Knife Designers

Roger Harrington is the founder of Bison Bushcraft and an experienced outdoorsman who has taught Bushcraft and Survival to civil and military clients for the last twenty years. His influences come from family involvement in The Scout Movement and his extensive travels around the world researching primitive living skills. He is also a Master Craftsman in the design and manufacture of knives.

The very popular Casström Woodsman knife was designed by Roger.


Alan Wood has been a professional knifemaker since 1985 and has become one of the UK’s most emulated craftsman due to his practical and attractive designs. Alan is also well known for his collaboration with bushcraft and survival expert Ray Mears, in making the Woodlore knife.

Alan has designed the Casström Safari Mini-Hunter, which has proved a hit with deerstalkers.
