To me the only similarity between a KA-BAR commando and the PAL RH36 is that they have six inch blades and leather handles. The KA-BAR is so much better made than the PAL. Pal has a zinc pommel, KA-BAR commandos steel pommels, PAL smooth leather handle, KA-BARs grooved leather handles, better grip. There were some parkerized PAL RH36s but they are pretty scarce, most are plain steel while all the KA-BAR commandos are either parkerized or chrome plated for corrosion resistance. Ed, I have the Union Cut dive knife, will try to remember to post photos tomorrow.
