The Birzman E-Version 15 Mini Multi Tool is a simple unobtrusive 15 function multi tool that is hard-wearing and constructed to get you back in the saddle quickly. All Birzman multi-tool bits are forged and CNC machined. This technology provides benefits including weight saving by using less material, increased strength, a centre tool pivot and a neater finish over the extruded wrapped tool bits usually seen on multi-tools. Tool bits are made from chrome vanadium. The side plates and bolts are made from stainless steel along with the Chain Tool that also includes spoke keys.
