The RK1504 flipper is available in two variations, the only differences being on the blade. The RK1504B model is a spear point design with milled fuller running almost the entire length of the blade. This flipper-only design with excellent action and ergonomics, is a staple of Rike knives. It shows the impressive quality that Rike Knife is currently bringing to the table. The 3.75" blade is made from CPM-S35VN stainless steel and features a black stonewashed finish. The handle is made from a machined 6Al4V titanium that also features a black stonewashed finish and matching back spacer.
