This custom Bold flipper Michael Zieba is an absolutely fantastic knife in every way possible. You're going to love the size, shape, flipping action, and superb fit and finish you get with this extremely precise handmade piece. Made in very limited numbers and Bold model is almost never available for sale. The 3.5 Bohler M390 stainless steel blade has a beautiful compound grind which gives you a sharp, hollow ground belly for slicing and a reinforced flat ground tip for piercing. It's one of the best-looking blades in the business and will perform every task imaginable extremely well. The chamfered handles are ergonomic in both the forward and the reverse grips and the hidden hardware on the titanium pocket clip is a very nice touch. The carbon fiber was made by custom knifemaker Matt Diskin and is widely regarded as some of the best synthetic material available. The blade rockets out on caged bearings with unbelievable speed and locks up tightly while the liner lock is still very easy to disengage. No lock stick, solid lock-up, fast bearings. One highlight of this knife though is not readily apparent at first sight. The ergonomics, build quality, and design are top notch. This is a beautiful yet tactical knife you will definitely be proud to carry each and every day. Blade Material: Bohler M390 Stainless Steel. Handle Material: Diskin Carbon Fiber. Pocket Clip: Titanium (Tip-Up, Right Carry).
