I need to cut out some warpy old chipboard in a bathroom to re-floor in ply. A small amount of it is trapped under a lightweight partition wall and so I can't use a circular saw. There is an external and an internal corner too, and it runs into a small alcove. I tried a floorboard saw and got worn out. There are pipes beneath.
Is there anywhere selling cheap ones at the moment?
