BM51BK: 51BK Morpho Bali-Song

Benchmade Knives raises the bar on Bali once more! A patented liner-sprung latch opens with a squeeze, yet locks open, too. Solid, machined slab construction is built on jeweled ti-liners. Heat-treated kicker pins keep things rockin’ hard and fast, and a practical blade shape is detailed out with a crowned blade spine. Others may get all the press, but Benchmade still owns the glory when it comes to Balis and the 51 proves it. Again.

Cons: Handle Material, Weight, None
Simply a great balisong.
The benchmade 51 is the baseline for any serious flipper. Yes there are more expensive/nicer blades out there, but for the price and quality the benchmade 51 is the place to be. Smooth flipping, great feel, seamless transitions, and excellent craftsmanship. The handles are a bit light, so you can always add some heavier scales the really enhance your flipping experience. Overall, you will not regret adding this knife to your balisong collection.

Very surprised with the mechanisms!
Love the locking mechanism. It’s very quick to open with it having a spring when you pinch the handles together then you can lock it in the open position. Didn’t know about this before I bought it. It’s sometimes hard to close the lock as the handles are flexible and you have to meet them evenly to lock it. Not necessarily a con but should be mentioned. Also really enjoy the pocket clip!

Cons: None
Great Benchmade Quality as usual
This is my first ever Bali-Song, so as far as how it performs as such I cannot really say. However this is not my first Benchmade and as usual the quality and feel is as good as ever.Shaving sharp out of the box much to the detriment of my fingers, but great to see. Feels solid when latched, which is impressive considering how fluid it feels when unlatched.The only minor complaint I possibly have is that the liner coloring is not as vibrant or uniform as seen in pictures. But one could argue this makes it unique, in the future I may go down the path of trying to color it some more myself.
