Hi everyone , here is a nice sunken joint Trapper I just finnished today . I used CPM-154 steel for the blade after heat treat an nitro quench an tempers I have a nice 60 Rc. The closed length is 3 7/8" with and open of 7". There is no spine showing or to feel when closed (Sunken Joint ) Nice burl Box Elder stabilized with and Inlaid Badge Shield and and a fileworked fluted bolster make this knife a stand out beauty. Blade lays perfect center and did so thru the whole work process ( Thanks to a Surface Grinder ). I do not notice any circles or rings anywhere after opening an closing up to 30 times, razor sharp and ready to work or go into a nice collection. will be posting in makers for sale area later. Thanks for looking an hope it makes your day in some way. Joe Allen.
