I was looking at the 5 myself, looks like one hell of a knife. Howes Knife Shop had them when I was looking, try there. I've bought alot from Jim, great guy and fast service.
Jim's great. He refunded my money on an Iuzula sheath that got lost in the mail. I ordered two ESEE Firekits from him today. Within 2 minutes I got an email from him that they would be going out today. Then we proceeded to have an email conversation about the weather. Nice guy.
