If I could carry a fixed blade concealed, this would be it. The blade’s profile is extremely comfy when worn IWB. The deep finger choil ‘works as advertised’, very secure grip. And the thumb serrations on the spine are as secure as on my Yojimbo. The sheath, however, is pretty bad. The retention is very loose, but the rattle is even worse. This sheath looks more like an FRN injection mold rather than a form fitted concealex sheath. The blade cuts like my Calypo jr., which is impressive given te increased blade thickness. I like to think of it as a ‘poor man’s Rinaldi TTKK’.
