It's not just at shows

Or knives, for the most part

I would coin it "perceived need"

If it's like me, when I find one that catches my eye, my thinking sort of goes along the line of "Hey, that's a nice knife, I can use it for doing..........." The reality, of course, is that any of my other 80 - 90+ folders would probably get the the job done easily as well. I have the same line of thinking with tools. Now, of course, this is very different to the the standard strategy of buying with a purpose - like collecting:thumbup:
My wife, when she really needs to make a point, is quite blunt about this, the odd time, though she does the same thing with her scrapbooking supplies (Heaven forbid I return the reality check - "Until death do us part would take on a whole new meaning

) My first experience with this was actually a long time ago when I started fly fishing. Of course, in the learning phase, I was catching everything but fish. I decided that better equipment was the answer and went out and dropped about $500 CDN on a new Orvis flyrod, of course, just for the browns on the Bow River. The response from my wife went sort of to the effect of "So.....you spent $500 on a fly rod that will probably catch nothing. Your $50 one catches nothing every bit as well" I'm bracing myself one of these on the pool cue I just bought
