The handles are skeletonized, made of a vibrant G-10 with blasted liners, and features a patented spring-latch locking mechanism. The handle also has finger contours for better grip, and a 6AL4V titanium tip-up pocket clip for easy carry. Despite an overall length of 9.25 inches, this beautifully crafted knife weighs just over 3 ounces, so it's easy to carry and effortless to use.

Great knife, well for the first few days anyway
Gregory S.
So first, I love this knife, has a great feel, looks really cool (wish I'd pulled the trigger back when the green one was being sold too!). My only comment against it is the cost. Not that it's crazy expensive, but that I also recently picked up a Bradley butterfly knife for less than half the price, and quality wise I'd say it's right with this knife. So part of what your buying is the name and reputation, but if this knife isn't in your price range you can't go wrong considering a Bradley. Note, the Bradley is a lot heavier. Now, all that said, so glad I bought the Benchmade as I've wanted one forever and this one will hold it's value given it'll sell out just like the green one did. Actually considering buying a second one to put up and not use. UPDATE. So I've been flipping this knife for a few days, changed my stars from 5 to 3 as the handles are already loose and the blade is making contact with the sides of the frame as it comes back into the handle. For this much money I'm shocked that my few hours of use have caused it to behave like a 10 dollar flipper.
Love these scales
Michael L.
Love the way this flips, love the bead blasted liners, was on the edge about the orange scales but found that I love the color and the hole pattern, love the stonewashed blade. I like this Bali better then my Morpho with the black scales, the scales just feel better. Hope Benchmade does more like these in the future, maybe with ti?

"Oooo the 51 isnt for flipping its too light" Absolutely not this knife! Im not sure if its the hole and the extra little weight but it is PERFECT for rollovers! First thing I did was crack this puppy open, did a Y2K and cut about an half a inch into my thumb next to my finger nail! So of course it comes hair popping sharp.
All I can say is that it is worth the money and it is absolute perfection from benchmade. 10/10 all around
Worth Every Penny

First off, this knife was delivered quickly, so two thumbs up to BladeHQ. The knife was in immaculate condition and very sharp. The attention to detail in this knife is incredible. I love the feel of the g-10 handles. It has grip when you need it. I'm no "Expert YouTube Flipper", but this knife flips awesome. I love handling this knife. It's a beautiful knife and worth every penny.
Favorite Knife

I bought this in person earlier this month, I absolutely love it. I use it as my EDC, so the pocket clip is nice to have.
My new EDC

I don't know where to start with this knife!! I absolutely love the color of the g10 scales!! The beadblast finish gives the scales the perfect texture for flipping. The long pocket clip holds the knife in place perfectly on the outside of my pocket (I live in an open carry state.) The blade is super sharp and the stonewash is gorgeous! I love the lack of tang pins. After watching reviews online I thought I was going to hate the design of the spring latch but after experiencing it in person it functions perfectly. I never thought I'd replace my Tachyon III as my EDC but this knife has done it.
Absolutely love it
Mark B.
I had the opportunity to pick this up in person at bladehq, so I was able to handle it before purchase. Orange g10 scales are bright and look so nice. They are very light, unlike my m42, so flipping will take getting use to a little. Pocket clip really doesnt get in the way either. Blade is VERY sharp and the stone wash is super nice. I'm very please with this purchase, especially since I missed out on the green one a while back. Get them while you can.
Brandon B.
Blade arrived a day early which is always a plus. Knife is very sharp and the edge is well produced. The G-10 liners feel great in the hand along with the 42 style holes. I love the bead blasted liners and pocket clip on this knife. The flipping is great but it seems like the pocket clip could get in the way during a few tricks but thats just me. That issue can be changed by also taking off the clip. Overall this is an excellent quality balisong and I look forward to progressing with it.
Quality balisong
