Just curious, firstly do they last (with maintenance obviously), are they easy to maintain and can they stand up to the kind of abuse that other materials (such as Kraton-G) can? When I say abuse I mean heavy use and sweat, or dirt or water etc. Also, is Kraton-G a good material to make handles from, because I understand that they are impervious to sweat and water etc. but I heard one person say that after a while of using a Kraton-G handled knife in the sun pretty much every day or second day for a year or so it when dry and crumbled. Does this happen and how can I avoid it? Thanks.
