I don't know if this helps, buy my Falkniven WM-1, provided by One Stop Knife Shop, did not come with the Tek-Lock, but was drilled for it. If I remember correctly, it was the neck option I bought, which provided the drilled holes in the event you wanted to optionally get a Tek-Lok separately from another company.
Give One Stop a call or email and ask what the story is on the Garm and Tek-Lok.
On the WM-1 - nice sheath work, nice knife, Thermorum material is comfy.
My only beef is the position of the drilled holes. After owning a similary sized Dozier, whose belt clip was located near center of the overall sheathed knife, the WM-1 Tek-Lock drilled hole position make this nice small knife's handle still protrude more than it should (from the standpoint of the handle end "printing"), which is too bad. So I compensate by wearing it solely as a neck knife.
