I was a diehard pen-tac spinner user,sure do miss Jed's company.I switched to Mor-tac after they were gone,but then discovered the Fishermans Shack (5038386395)they also can be viewed at www.proaxis.com/~fishshack.They have a far superior plating process than Mor-Tac,They also have the thick thumping blades youre looking for.you wont be dissapointed.
