Took possession of my Ikon Slant yesterday. I was very impressed by the look of this razor. It has real heft and the quirkiest head you'll ever see. I loaded it with a Feather blade, lathered up with Proraso cream and set about my two-day's growth. My beard is moderately thick and I was very impressed with this razor. In fact, I was blown away by the shave, which was as quirky an experience as the appearance of the head suggested it would be. For one, I've never experienced feedback from a razor quite like it. The sound was very loud and, well, strange! Perhaps the bend of the blade produced this peculiar "singing". I assure you, this will be a totally new sound to you.
I did three passes and was hugely impressed with the results. BBS on my face AND neck. I recently sold all my DE razors because they couldn't compare with my Cobra Classic. This DE razor is a game-changer though. Without doubt, that was the closest shave I've had with a DE. One thing that surprised me was the nasty weeper I got on my neck, behind the jaw line, when I did a XTG pass. I've never had a weeper from my Cobra. With the Cobra I don't need to pay much attention and assumed I could be as cavalier with the Slant. Big mistake.
If you are wondering whether to take the plunge on this razor, I'd say go for it. The original head will provide you with a truly unique shaving experience.
