Really interesting video, thanks.
Don't forget the particular application for that knife, being an antartic research mission, which would inform the choice of blade material, size and shape and materials of handle and or sheath too. While an O1 bladed, wooden handle and leather sheath for example would work in that environment too, the choice of actual materials and design suggests a very functional, low maintenance and long lasting tool for use with thick gloves on and in a wet and cold environment ?
I've got a spare motor knocking about getting in the way....... :-k (hammer)
