For my first post on this or any other knife forum, I'm requesting any possible info on the M16 Special Forces knife form Columbia River Knife and Tool. I'm looking to make this my first non Swiss Army Knife and I'm very taken with the overall look of the knife. However I have some concerns about how practical a tanto blade is. Can it thrust and pierce, and what about sharpening. Any info would be greatly appreciated. This community is brilliant, and has already provided me with a wealth of useful information. Thanks a lot.
