OK I thought;seems to me I have a couple of three backspring knives around somewhere.Upon checking it seems I have more than a few but I'll post them anyway.
First up is a Henry Sears 1865 with a strange blade arrangement(2 blades in one end and one in the other)and some of the strangest colored bone I've ever seen(browns,reds,grays,yellows)and a pattern I can only decribe as a humpback stockman for want of a better term.
Second & third are a couple of High Carbon Steel USA 5 blades with the master blades etched "Craftsman" STA-SHARP barely visible.One has a propeller shield and the other a badge type.Beautiful jigged bone scales.
Fourth is a stag scaled multiblade with shotshell puller bolsters marked,"Tonerini Scarperia". The file work is mine.5 tools.
Fifth is another stag scaled multi marked,"Aitor Made in Spain".8 tools altogether.
Sixth is a gardener's knife by Frederich Hartkopf with ebony scales and clip master blade;pruner;saw;and broken off Seton's needle.
Seventh is a Mikov stag scaled multiblade.
Eighth is a Kershaw 5 blade with G10 style scales.
Ninth is an IXL Horsemans knife in near mint condition.I bought this one years ago for $25 and it was a bargain then.
Last picture is a group of multiblades together.The two really big ones(10 and 13 backsprings respectively)are Pakistani and Italian.The Pakistani one is essentially 2 five blade knives put together.Construction isn't bad and it was cheap;I bought it at a pawn shop for $10 in the original box. The Italian one came in a trade from a friend and is totally impractical;except maybe to put in a heavy woolen sock and use it as a club.
