I really like the GI Tanto as an inexpensive and quite indestructible fighter, but only when outfitted with the new, simple but well shaped plastic grip scales. However, they are on the slippery side.
Two strips of skateboard tape help to remedy that completely. The grip is now quite abrasive and stays absolutely secure in your hands, so when using the knife intensively in the outdoors ( I do not consider it ideal for that ) you might have to peel it off again. No big deal.
