Hi. i reckon that i know a fair bit about knives, but this prblem has stumped me. i was watching Lost on tv and couldnt help noticing the knife that John Locke (actor Terry O'Quinn) carries around with him. it is a large knife, and vaguely similar to the randalls adventure knives made by ontarion. i would really like some help with this because it is beggining to bug me! thanks!
