I've been struggling with cutting leather since I got into this hobby. I've tried a Japanese style knife and found it far too alien from my normal knife grip to be useful, I tried utility knives and found them too awkward for anything but straight cuts and I tried hobby scalpel/craft knives but they require a finger grip similar to a pencil which my arthritis doesn't allow, I also found the blade flex difficult to mange on tight curves. Since I also work in wood carving using a Mora 122 knife I decided to try a Murphy Sharp Point Leather knife No. 2 with a 3 1/8" blade which is similar to the Mora but with a much thinner blade. What a difference, I can now make straight cuts with ease and following pattern curves is a snap. No more wrist discomfort or grip fatigue and my grip is now consistent between the two hobbies.
