Great knife

I was not sure what to expect with this knife. The reviews I have read all said this is the best BM42 clone out there and they are correct. I own a BM259s a Kershaw lucha a pcc (Pacific cutlery company aka benchmade) 159 and have owned many others. The one BM42 is a great knife at a great price I highly recommend it. Shipping was fast and the store is on the level. I will definitely buy more. Thank you slash2gash you guys are awesome.

Classic 42 "the one"

The knife is good... I have many other "high end" balisongs. It flips and feels better than some of them by far. It came with the bushings too small but that was quickly fixed with one email. They immediately sent a new hardware kit. Customer service was outstanding! If your looking for an inexpensive flipper that feels like a high dollar knife and enjoy tuning and/or customizing your bali or you just want a 42 and cant find them anymore... You will NOT be disappointed in this knife. Get one while you can!

Fast and great service

First of all very fast shipping and service. I order from multiple online knife companies and S2S has blown them out the water. The knife is exactly as described, and sharp. I even got a little hand written reminder to put loctight on the pivots. I will definitely be doing business with them again.
