Yesterday, tossed the KAI with 15 shaves. While the shave yielded BBS with no discernable irritation or nicks, there was some dragging and too much touching up needed.
New member here. Astra SP (4).
Great blade, but seemed to be running out of steam after four shaves.
I'll continue to work on my technique, though based on cost, I'm happy to pop in a new blade at this point.
After shave number 33 I tossed a Gillette Silver Blue. I think it still had a few shaves more left in it, but the razor (D1 Flare Tip Super Speed) was ending it's weekly rotation., so it seemed right. If this isn't the most I have ever gotten out of a blade it's close.
