Can someone tell me more about the titanium alloy used in the Problue KN-57T?
Junhao Lo –
The KN-57T Titanium B.C Knife features a 3-inch titanium alloy blade. Titanium alloys used in knife production are often referred to as Grade 2 (Ti-3.5Al-5V-5Mo-5Zr) or Grade 5 (Ti-6Al-4V) alloys. These alloys are prized for their strength, corrosion resistance, and lightweight properties. In the case of the KN-57T, the exact alloy composition is not specified. However, based on the product’s features, it is likely that the blade is made from a high-strength titanium alloy like Grade 5.
