No, not wrong. There are all sorts of tools you could use for this job - and if, like me, you're watching this because you just have one picture to reframe, it makes no sense to buy a quite expensive new tool for the job that you'll never use again. I can think of plenty of "tools" I've already got that could work fine - from the obvious screwdriver or chisel, to a much wider plastic scraper (from a £ shop - dirt cheap) to the handle end of a kitchen spoon to an old plastic washing-up brush (cut/shape the handle end, cut off the bristles - it's a similar shape to the Fletcher tool but much bigger - easier to grip, better control, more power). As the old saying goes, "there's more than one way to skin a cat". Whatever works for you. Thanks for the video - it was all I needed.
