F1d is a slightly special version of our classic F1 model. We have not only changed the color of the handle and the blade, but also added another steel, namely our now famous laminate cobalt steel. The bottom line will be a tough, good-looking all-round knife with a blade that retains its edge extremely well but which is also strong and capable to stand incredible strain. F1d will be available in this particular combination only, I e a light sand-colored handle, a black blade and a safe plastic sheath in zytel. Looking for a little different but at the same time secure knife, the F1d might be your best choice. The new injection molded zytel sheath offers a neat safe and strong combination of qualities which should be very attractive to any user.
