Query: Fantastic knife!

I bought my SOG trident tanto a little over a year and half ago, and since then its seen some heavy use. The Trident has stood up to the abuse with no problems whatsoever, the edge and finish have both held up through all sorts of various uses, from cutting rope to cutting wood. Even the assisted opening hasnt aged a day. This knife is fantastic and has served me well.
