I've bought a lot of knives online, and I have been disappointed with 1SKS.com.
While thier prices are competitive, thier service for me has been poor. They take forever to ship and order, and also take a long time to follow up with questions... such as "when will you ship my order?"
I once placed an order, and unfortunately changed my mind. I sent an e-mail asking to cancel the order, and asked for a reply. After several e-mails, it became clear that, while they hadn't charged my card nor shipped the product, they were clearly not talking to me. I just found that really poor.
My money goes to knifeoutlet.com, and some other places as well...
I might say that if you don't mind the waiting, then you can shop here, but whenI plunk down my money I want the thing asap.
Cheers,
Bill
