Maybe useful for a DIY project:

Now FT has a lot of Tekut knives. Here are only a few. Tekut uses 7Cr17MoV steel for the knives and not the 8Cr13MoV like Sanrenmu or Enlan. SOG uses this steel in a few knives.
I don't own a Tekut and would prefer a SRM if the design is similar, because SRM would be cheaper and I like the quality of SRM. But Tkut have some designs, which looks interesting.
