I have an older German made Stockman style knife, 3 blades and stag scales, where the main blades comes opens like a switchblade when you depress one of the other small blades. Problem is the metal piece that provides tension and holds blade in place when open has broken. I guess you would say it is the long pieces that extend from bolster to bolster in the spine of back of knife? Anyway is there anyone here who would entertain repairing this knife for me in the central Texas(Liberty Hill) area? Guesstimate of cost to repair? PM me and we can discuss or I can send pics for evaluation. Thank y'all.
