Expanding our growing range of CSTM.-izable knives, we’ve added the iconic Barrage® to the list with the new 580 CSTM. Barrage®. Originally designed by esteemed knifemaker and regular Benchmade collaborator Warren Osborne, the Barrage® has been a standard-bearer for reliability and utility for years and actually served as the debut platform for our AXIS® Assist mechanism. Using Benchmade’s Custom Knife Builder, you can now build your very own Barrage®, free to explore the dozens of combinations of premium materials, exclusive colors, and personalized laser engraving to craft the 580 CSTM. of your dreams. Designed By You, Built By Us; Yours, For Life.
