Google RAT and Ontario. These are Randall of Esee fame before he started Esee, if I remember correctly. Good knives, but Esee is superior, I believe Randall was not happy with Ontario quality, so he broke off to form Esee.
D2 and 1095 are both good knife steels. Google them also. D2 is tool...
No! That would be like bringing a knife to a gun fight. Do not do this. It will bring you badjuju. Just buy the knife and keep your gun. However, I do love knives.
