I have owned 5 different Benchmade balisongs and they are always of very high quality. This one is no different! the 51BK-1601 is my first limited edition Benchmade, but will certainly not be my last!

So I got mine for around $150, plus tax, but it's been my personal favorite Bali-song they make! Now don't get it wrong when I say it's not the most expensive knife... but with a price tag of around $300/330 it's kinda expensive, but you definitely get what you pay for. It's also a nice and light weight knife so it can be used as an EDC, flips very well. And the balance it has is amazing!!! But just take my review, and if you buy one see if you agree with me. I love this knife I'm never getting rid of it
