All About Pocket Knives

I have a Buck 110 in a Type A Sheath that is around 50 years old and is used but not abused. The blade feels loose when I go to lock it up but locks up fine, I am thinking years of use, opening and closing a thousand times wore something out.

The old Buck 110, before the various two dot, three dot, four dot models were like that once used. It is normal and okay if the blade is locking up tight (as you mention). In fact the knives were popular as "flippers" and Buck made the original two dot change to eliminate what you describe. Good old collectible and using knife! OH

Thanks
