Just encountered this and couldn't resist posting - more for grins than anything else - http://www.soloscientific.com/soknbysoscpp.html?gclid=CKCk6KS3qcQCFYhgfgod0V

Maybe this gadget is great,but I will reserve judgment for a bit. But just think of potential embellishments - a luxury steel (at least S90V), partially serrated blades etc. - maybe a folding variant. The mind reels as we enter the solar age of survival and bush craft....
