Even fully open, the Old Timer Dog Leg Jack pocket knife only measures 5.00" long. But with two blades (2.25" clip point and 1.5" pen blade) you'll get double duty from this knife. Super light weight, it will fit in a pocket or purse for convenience. But don't let the size fool you - that touch 7Cr17 high carbon stainless steal means this pocket knife can handle big jobs.
