This is a large knife. Can't find much about it. It is automatic, push the button and it opens, no locks. It says Made in the USA on the box. Be aware of your laws before you make an offer. 150.00 or best offer. I'd also be interested in swaps, maybe a Benchmade or ZT or? Price includes shipping in the conus. The ZT 0550 in the pic is for size reference only and is not for sale.
