Hi all, sorry if it's a dumb question but is it normal for a Marshalltown trowel (not a flexi) to be curved across its length from new? I know they are 'broken in' so expected a curve across its width but against a straight edge the heel and toe are lifting about 2mm up. I guess it will stop it digging in and maybe straighten a bit under pressure but is that normal as I kind of expected them to be flatter?
