No sold-price aggregates are published here yet, and this page does not invent them. What it gives instead is the framework that decides value: which class the razor falls in, and which details inside that class move a price.
| Class | Years | Market data | What drives it |
|---|---|---|---|
| Common user-grade Gillette safety razors — Tech, Super Speed, Milord, Knack | 1938–1980 | No sold aggregate published — retail asking observed only | Plating condition, a straight handle without cracks, the presence of the original case and the blade pack. |
| Collector-grade Gillette — early Old Type and Double Ring, Aristocrat, Sheraton, Toggle, Fatboy, Slim and the adjustable rarities | 1904–1968 | No sold aggregate published — retail asking observed only | Rarity of the variant, the originality of the plating, the correctness of the case for the set, and whether the adjustable mechanism works. |
| American single-edge and injector razors — Gem, Ever-Ready, Schick, AutoStrop and Valet | 1898–1970 | No sold aggregate published — retail asking observed only | The model rather than the brand, since a common razor is cheap and a rare variant is not, plus completeness of case and blade magazine. |
| Straight razors by maker and condition — Sheffield, Solingen, Thiers, Eskilstuna and the American schools | 1800s–1900s | No sold aggregate published — retail asking observed only | The maker, the survival of the tang stamp, the width and grind of the blade, the integrity of the scales, and the cost of restoring it to shave. |
| Boxed sets and outfits — cased Gillette sets, Rolls Razor kits, the Wilkinson seven-day set | 1900–1970 | No sold aggregate published — retail asking observed only | Completeness: the correct razor in the correct case with the stone, strop, blade or papers it was sold with. |
| Modern-vintage and current production — Dovo, Merkur, Thiers-Issard | 1906 to the present day | No sold aggregate published — retail asking observed only | Which line it is and whether it is new stock, rather than any claim about age. |
