These are brand new High Speed Steel planer/jointer knives, that measure 12 X 7/8 x 1/8",  in a set of  3 knives.  These knives will  fit the Parks, some Powermatic and other 12" machines.  Please measure your knives very carefully before bidding, to insure correct size.  The knives are made of high quality, High Speed Steel material, heat treated to and ground to industry standard tolerances.  The HSS steel can give the knife a much longer edge life than other materials. 
Please consult your machine manual, or measure your existing blades to verify correct size.  Please ask any questions before bidding. Seller will ship promptly after payment clears.  Please feel free to check my feedback for any concerns. 
If you do not see your size listed in any of my auctions, please email your specific size for a price.  We can supply blades in both  High Speed Steel and Carbide Inlay for most planers and jointers.
