In this knifemaking vlog, I continue the build on my framelock flipper folding knives, diving deeper into precision machining and problem solving. I start by finishing the backspacers, then move on to cutting stop pins and pivots to final length for proper fit and function. Along the way, I run into a major issue with the twist damascus framelock — a costly blunder that could have ended the build. I break down exactly what went wrong, how I diagnosed the problem, and the steps I took to salvage the framelock and keep the knife moving forward. This video also covers: Pivot length setup and pivot adjustment details Stop pin sizing and fitment Layout, drilling, and machining the lockbar start and stop points Cutting clean, accurate lockbar slots Real-world lessons from hands-on custom knifemaking Framelock building playlist: https://studio.youtube.com/playlist/PL3J5OXaYrzvTmfsS4J46JJjspcib1MlFj/videos Knifemaking Playlist https://www.youtube.com/playlist?list=PL3J5OXaYrzvSu9Y9O1VvqcTBrFlXcrB_1 Damascus making Playlist https://www.youtube.com/playlist?list=PL3J5OXaYrzvQmX2JoRJC710cppxj7Iq2T Song: I-85 Artist: Kia Music by: CreatorMix.com 👉 Subscribe for more knifemaking tutorials, shop vlogs, and behind-the-scenes builds. 👉 If you enjoy knife making vlogs, custom folding knives, or want to learn more about the tools and techniques behind high-end knives, don’t forget to like, subscribe, and comment with your questions!
