You know how haggling is accepted practice at flea markets, and yard sales...seems thats where I find my best deals...even though those deals are not the find of a lifetime...just because I got them cheaper, I walk away thinking I did pretty good!! and the guy that sold them to me was maybe thinking the same on his part!! Then I take my sweet $1.00 "deal" and store it in a shoebox with all the other "great deals" and try to sell them at my yard sale for $5.00 knowing I'll get haggled down to $2.00. Seems no matter how many yard sales I go to, I most of the time find a $1.00 pocket knife, and I justify myself as at least buying something from them to be polite.
I did buy a few over the years that rise above the shoe box....even though still they are not rare or special edition.
One is a Push Button Knife Co. Walden N.Y. a hefty 4 3/4" jigged brown bone trapper with a pushbutton release single N/S bolster and has a fold-away finger gaurd. YEP...got her cheap.
Also, I'm proud of my jigged brown bone Camillus rigger...and my other rigger an all S/S West Products U.S.A. Sealine.
Of Brand new deals...I recently wanted and bought a new Kershaw 1050 folding field knife. I searched everywhere and ended up paying $130 which I thought was a good deal....then on eBay I found a Powerseller called Razorsharpknife who has the same knife for $105 buy it now price...and the fixed blade counterpart 1030 model for $80 BIN price. I like Kershaws and Schrades, and I'd stick with eBay for some good deals there. I think if you are patient and keeping an eye on things, you can do well.
Surprizingly, I find "good deals" at Pawn Shops too.
