I assume we're talking about the newly offered Gauntlet sharpening system and, if so, I really don't understand what the Gauntlet offers that the Sharpmaker doesn't offer already.
The Gauntlet only comes w/a pair of fine rods w/the Select version ($80 MSRP) and a pair of fine and CBN rods w/the Premium version ($165 MSRP). On the other hand, the Sharpmaker comes w/a pair of fine and medium rods for $105 (MSRP) and you can also purchase additional rods for it, including ultra fine ($25 MSRP), CBN ($82 MSRP) and diamond ($82 MSRP), which makes it far more versatile than the Gauntlet.
So, I wouldn't even think about buying the Gauntlet unless the elliptical shape of the Gauntlet rods is markedly SUPERIOR to the triangular rods offered w/the Sharpmaker but, given the results that I already get w/my Sharpmaker, I don't see how the results w/the Gauntlet could be THAT much better, especially in my clumsy and inexperienced hands.
However, I'd certainly be interested in seeing/reading/hearing a comparative review of the performance of the 2 systems using the same rod material (fine and CBN).
