I have a strop but have not yet used it. I bought the razor on ebay, here is some of the ebay blurb,
"This is an 11/16-width square-point, wedge-style or half-hollow-ground John Bylde straight razor made in 1885 or earlier in Sheffield, England, the world capitol for fine barber's razors throughout the 19th Century. The horn scales are in virtually flawless condition; one one side in cursive is lightly etched, "Francis Laurie 1885."

The hardy blade is in excellent condition with the original factory satin finish. It's stamped on the tang with an image of Saturn and EXTRA HOLLOW GROUND is etched clearly on the blade's face. The blade is firm on its pivot pin and must be closed by hand; it won't fall shut by itself. It closes straight and centered, without wobble, between the scales.

With proper stropping and use this razor shouldn't need to be sharpened any time soon, because I've already run the blade over four grades of diamond hones, polished it on a surgical-black Arkansas stone, lapped it on balsa blocks treated with two grades of diamond grit and one treated with fine chromium oxide, then stropped it 50 strokes on American latigo leather. Afterward I wiped down the entire razor with a silicone-impregnated cloth to add a moisture-shedding coating and applied water-displacing oil to the pivot pin.

The edge is sharp enough to cut a hanging hair at multiple points. I sell only shave-ready razors because I'm not a collector, I'm a shaving enthusiast, ..... " etc.
I did not strop before shaving as this razor was advertised as 'shave ready'. My shave prep was probably inadequate; I lathered up after a hot shower but did not apply anything to my face before. I'm not sure I understand the difference between 'tugging' and 'resistance' however.
