Super helpful
Where has this little triangle been all my life? I do fine scale modeling, primarily in metric dimensions, and this fills a need I have had for a long time! It makes "inside corner" measurements and layout much easier, is sturdy Stainless with Imperial markings on one side and metric measurements on the other. Small enough to put in your pocket, a bit thin at times, but I just back it up with a 1-2-3 block and it's all good.

Durable Triangle
This is the right size for HO scale modeling when trying to make things square and mark off a cut line. It's being thin is an asset as is its being medal as you can run a hobby knife blade along it for a precise cut.

Perfect points.
Functions as expected. Makes pressing points a breeze. Light weight. Sturdy and durable. Easy to use. Just wish it had a hole to attach a ribbon to pull it out of the point since it is hot. I yused it for Dresden plates.

Never knew I needed one
Got it thinking it was larger. Then one day used it in a very tight spot. One of those things you never knew you needed, till you did.

Handy size for model work
Clear, easy to read markings, thin yet sturdy metal. Handy for trimming decals, strip styrene or basswood.

Accurate and so handy
I work as silversmith and use these triangles every day. They hold up well the past year I have been using them. they could not be much handier except maybe increments on the long side.

ZONA - ZON37433 Zona 37-433 triângulo, aço inoxidável, 7,6 cm
O esquadro é muito bem feito, tem marcações precisas. O problema é que ele é muito fino em sua espessura. Acaba sendo um produto frágil. Deveria ter pelo menos 2mm de espessura.
