Blundell Harling Portland Triangle 200mm

I bought two so I could use them as a pair and they are less prone to slipping than parallel rule. Not yet tried them on a boat but looks promising.

We use these all the time at sea and these are not in the league of the ones we use.However they are fairly priced for what they are.Pretty sharp as sides are not rounded so keep the packaging if you remember to wrap them.

Does everything I want.

Good as expected

Does the job handle is a bit flimsy but other than that are a good size
