Welcome to the Yard! Dan’s knives are in VERY high demand, with the entire stock selling out in mere minutes sometimes. If you want a chance at a new model when it’s released, your best bet is to check the forum a couple times a week. Dan posts a notice before a new knife is released, so then you’ll know when and where before it’s listed for sale.
The
SS4 is a great knife. You’re best chance at one is probably eBay, Blade Forums, or the
Busse Kin Exchange.
