For a while now, I have been trying out different edge finders, and found that none of the ones offered came up to challenge the accuracy of my 25 year old Starrett imperial one. In fact all of them gave either way out or unrepeatable readings.
Now came the time I was looking for a metric edge finder. I know that Starrett do them, but they are rather expensive.
So when Arc Euro started to advertise that they had got two new metric ones in, I decided, because I had never had a bad bit of kit from them, to give them a go. So I duly bought one of each, a 10mm and a 4mm one, at 5 squid 50p (about 10 bucks) each.

I hadn't even tried them out, as I have been too busy, but when Ralph came over last weekend, he asked me what they were.
I duly explained, and with Ralph looking on, they were put thru their paces, and compared to my faithful Starrett.
Both came thru with flying colours, giving repeatable results each and every time.
I was so impressed with them, they now sit proudly with the Starrett on my tooling rack, ready for action.
