Reciprocating saw with masonry blade - breeze blocks

[Draughtsman]

Would a £70 Erbauer reciprocating saw be ok for cutting out a doorway in a single leaf internal breeze wall, using masonry blades? The masonry blades aren't free but I won't have cutting discs in the house, they're banned. Not a supporting wall.

Thanks

You're not wrong.

Good for stitch repointing horiz mortar cracks too. Theres's a ring beam at ground floor window cill level, no cavity below. The (ground floor) bathroom wall tees onto it so it's the same temp as the outside wall in winter, but it had a rad so the top 3/4 changed temperature/width with the rad all winter whilst the wall base remained freezing. It popped a mortar course just below top of rad eventually, all the way along.

You can cut along the ctr of mortar, slide the loose bit out, and chisel out the remaining from either side of the wall without too much difficulty.
