Never thought I’d own a BM42

The benchmade model 42 was my grail balisong growing up and I always wanted one but could never afford one. By the time I could afford one they were discontinued and I wasn’t about to spend $600 on a balisong. TheOne allows me to feel what it would have been like to have the money for an original when I was a kid. Solid build quality, great tolerances, spring latch works great!

The one 42

The knife came razor sharp well made and overall above and beyond my expectations. It along with the hardware kit I bought arrived timely. I will be shopping with you guys again regularly.

Great product

Good quality, perfect blade play, what more could I ask for?

Decent knife, seriously awesome customer service

This isn't my favorite balisong due to the tolerances and the weight, but at this price those are acceptable.
What I'd like to really emphasize is how accommodating Jeff is. Without any prompting my order was upgraded to one-day shipping so I got the knife insanely fast. On top of that, after having it for a long time and deciding I did not want to keep it, Jeff talked to me about ways I could better time the knife to my liking, and ultimately offered a full refund. Cannot speak highly enough about the company and Jeff, even if this specific knife wasn't for me.
I'd recommend saving up for the titanium versions, but you cannot go wrong doing business with Jeff and Slash2Gash.

Exactly what I was searching for

I literally searched up "channel construction balisong" and this was one of the first results. I didn't expect to find a great price, high quality balisong in the exact classic b*******e 42 style I was looking for, and this exceeded my expectations. Checked off all my boxes, those being mirror finish, channel construction, spring latch, and the signature holes in the handles. A little on the heavier side but that's good for me as a flipper since I feel more confident with a heavier knife. Cutting edge starts nice and high so it's safe for certain tricks where a finger might touch that unsharpened bottom part of the blade. I understand design constraints but I wish the edges of the handles were fileted a bit more so it rotates easier, I find myself getting stuck in the middle of tricks where a rotation around the thumb and forefinger is required, but I'm sure that's something I can work around and get used to. Strong buy 5/5
