I've got a chance at an old timer 44OT, nib. could anyone tell me anything about this knife?? I've never seen one of these. here's what i know so far, made from 90-93, and a limited run in 2001 with a blade etch of some type. and this is one of very few old timers with 4 blades. okay that's all i know so any help would be appreciated. thanks, ahgar
