The Leatherman web site says the Free K4 comes with a sheath. However, the K4 I bought at Bass Pro Shops (in Illinois) did not come with a sheath in the sealed box.A phone call to Leatherman claimed that retailers can package the K4 with or without a sheath. Ugh. One pleasant surprise is that the supplied pocket clip can be attached to either side of the K4 for left or right pocket carry.(Image removed from quote.)
Sabre hollow grind? Is that even a thing.
The K4 blade is a sabre hollow grind. Using a digital calipers, I measured the spine as 0.125 inches (3.18 mm) thick along most of its length.
