Found these in Walmart paint department today. Certainly not the best scraper available, but considering these are regularly priced at $2.23, with 5 razor blades included, and made in USA, inexpensive enough to keep a few laying around. Home Depot sells the same scraper for $6.75.
Hadn't any issues with that tool.
Looks absolutely exactly like the Stanley 28-500 (Art. 0-28-500), even small manufacturing details look identical. The original Stanley is stamped "STANLEY No. 28-500" above the round hole. Swiss price incl. 8.1 % VAT corresponds to around USD 8 to 10, I'd have expected it to be way more expensive than (U.S.) Home Depot as comparison, typically Swiss prices are often 30 to 60 % higher than German prices (comparison excl. VAT). I purchased some tools in the U.S. and they were much less expensive than here.
I use some larger Tajima scrapers, quite good but expensive, though I haven't used their small scrapers.
Referring to Stahlwille, many generic tools are not manufactured by Stahlwille and are way less expensive if the original are bought, e.g. various items from Bessey, including Erdi, or Rennsteig (1:1 excepted the labelling and sometimes grip colors). Even Hazet used to be a supplier though I don't know if it's still the case. Also the adjustable 4025 and 4026 wrenches are usual models from Irega, the only European manufacturer of such wrenches.
I don't know Stahlwille scrapers well enough to tell if they're original Stahlwille tools or only private-labelled.
