Alameda,
hmm, written in Spanish ?? Well, living/existing here in SoCal does provide a necessity to be bilingual, and Spanish is almost a necessity sometimes.....
Anyway, I'll look around for the complete writeup I did about The Method.
In the meantime, young feller, not only am I old enough to know about barber chairs and leather strops, I have my grandfather's leather strop that he bought way back about 1918 or so !!
Yessir, an oldie and still a goodie.... both me and that leather strop.
The Spyderco kit does things different and is very effective and efficient at putting sharp on steel.
And as Robbie says, stropping isn't necessary to get a razory edge if you're using a sharpening setup that will provide a razory edge.
Stropping just makes it sharper..... maybe/sorta/I couldn't say for certain. But with The Method, stropping smooths out the rough, but very sharp, edge created by the Smith's plastic thingie. My pal Tim calls me "obsessive" .....
Cheers,
Carl
