The EX10 Balisong is a unique knife created by Geof Dumas Original Knives. Geof Dumas is a skilled knifemaker who specializes in making top-notch balisongs for those who enjoy flipping knives. This particular version of the EX10 is a special collaboration with Jon Sorenson of Rotten Designs, who expertly crafted the blade grinds on these knives. The EX10 features a titanium handle and a beautifully finished clip point blade. It's important to note that after a break-in period and tuning, it's recommended to use thread locker on the pivot screws to ensure they stay in place. Like all Balisongs, it's a good idea to regularly check and tighten the screws.
