Too funny, I have the same exact strap wrench. In this case, I wasn't able to get it to grip well with the small surface area. The Irwin clamp happened to work easily and didn't damage the surface. Just wanted to give people a heads up of another potential tool to use. After breaking my last lens with the combination use of a vice clamp and induction stovetop; I figured I'de share something that worked this time around. But I agree, those strap wrenches are great!

I too, was about to give up with the strap wrench. Then, on the last try, it worked. Effectively, the irregular shape of the flip holder prevents the wrench making a firm grip. With the Irwin clamp you are able to apply the force on more specific spots.

it ended working for me ages ago but defo water vigenar helped with freezing and hot water too and yes i used my old leather wrench
