IPSmart 31745 Shinwa Japanese #19 Stainless Steel Protractor 0-180 Degrees with Round Head by Shinwa

Herramienta muy útil en el taller de carpintería para dibujar los ángulos

The accuracy seems excellent, the markings have maybe 0.1~0.2 degrees inaccuracy at most. The edge is perfectly flush at 180 and 0 degrees.One really nice and innovative feature I noticed is that the indicator arm with the measurement mark is ever so slightly bowed in the vertical plane, like a 0.05~0.1 millimetre and only makes contact with the protractor BEHIND the measuring arrow. This means that throughout use, as long as you don't overtighten the locknut while measuring, it will significantly reduce any wear on the indications and measurement marks since it's not making contact with them.The locknut holds the entire thing together so don't overloosen it, a small 1/4 or 1/3 turn is enough and provides that gap underneath. Very happy. No idea where it was made as the packaging doesn't actually mention on mine, but even if it's made in China it's pretty solid quality. Would have liked to have it made in Japan but oh well. The description is incredibly misleading though, the only Japanese thing about this is the brand behind it. Given that that's the only indication anywhere on this page for where it's made I find that misleading as anyone browsing (like me) would assume it's made there.

Solid well built protractor. As far as I'm able to tell its very accurate as well.

E' costruito molto bene per l'utilizzo in officina meccanica e risponde a pieno al descrittivo dell'annuncio. Consegna come sempre ottima.Giuseppe

Goniometro che ho adoperato tempo fa in un'officina non mia e con il quale mi trovavo molto bene.Dava l'impressione di essere ben fatto, sufficientemente solido e con le scritte resistenti alla sporcizia ed agli agenti chimici.Dimensioni adeguate, né troppo grande, né troppo piccolo.Ben fatto anche il dispositivo di serraggio.Avevo quindi deciso di acquistarne uno per me, malgrado il prezzo un po' troppo elevato.Purtroppo l'oggetto non è mai arrivato, come molto spesso accade con le spedizioni dalla cina.Segnalato il problema, ho ottenuto il rimborso.Peccato.
