How many shaves are people getting out of a Nacet?

Seems like things deteriorate rapidly after 4 shaves based on the first blade trialed. Any others with more sight pictures on this blade?

Like nacet a lot. Sharp and smooth but my experience will match yours. 3 or 4 shaves and done.

I usually bin a blade at 7 shaves max if it can make it and rarely these days exceed 5.

I don't use DE's very often but my understanding is the Nacet is quite sharp so like the Feather I would have assumed 4 shaves would be pretty good. It seems strange to me but I recall coming across a guy on YouTube with over 200 shaves with a Nacet along with surprising results with other blades as well.

I usually get 4-5 shaves from Nacet blades.

The first ever Nacet I used I took up to 11 shaves. It was impressive.

After that one, I’ve been using them up to about 5–7 shaves. (It might be good to add that I only do two passes per shave.)

You are wise to define the metrics! Please to allow a clarification of the original post:

“Seems like things deteriorate rapidly after 4 3pass shaves based on the first blade trialed. Any others with more sight pictures on this blade bearing in mind that am essentially getting 12 good passes/blade and so framing their results in that framework?”

But are the 2nd and 3rd pass as demanding of the blade as the first?

I toss it after 6 - a week's worth.

But are the 2nd and 3rd pass as demanding of the blade as the first?

This is something I’ve often thought about, and I would imagine that they are not – especially if shaving more than one day of growth (well, depending on stubble growth rate, of course). Often, the first pass is expended clearing away some serious wire for a much smoother second pass.
