We where very happy to get our hands on these visually striking carbon fiber wa handles. The material is set in epoxy. This handle will fit most knives 80mm - 150mm. The tang hole is small and will require a bit of material removal with a file to get the right fit. Or just let us install it. We waive our $25 install fee if you buy any blade and handle from us . This handle is not recommended for at home installation!
