Hello guys I am wanting to purchase a fixed blade knife to keep for many years. I would like to have some input on metal type and model. I am considering the: Ka-bar Ka1461 in spear point in D2 steel, Gerber Yarinin 154cm steel, Camillus cmbk2 in high carbon steel, Knife of alaska -cub bear in D2 steel. Does anyone have one of these knives that they might want to tell me their opinion of and which metal would be the best for every day use ? Thanks for your help guys . Jay
