No, really why? .......
Most other non vintage blades give me no more than 4 to 5 shaves before needing a change out. I manage 9 to 10 with a 1960's Spoilers.
I have access to a portable X-ray Fluorescence (XRF) device and was able to analyse the alloy used as stainless steel grade 410 (85.5% Iron, 13.99% Chromium, 0.44% Manganese, 0.06% Molybdenum). These recorded values will vary slightly from batch to batch, and from reading to reading on the same blade sample.
From what I know, most other stainless steel blades, both vintage and modern are also made from 410SS strips. Checked a few other brands with the XRF to confirm this.
I can only assume that Spoilers were thermally processed to a higher degree of hardness thereby allowing them to stay sharp longer. May also have something to do with the quantity and quality of the Teflon used on the cutting edges.
Any thoughts?
