How, with what, do I cut a thick beam most easily

[Trelleborgbyggaren]

Hello
I have demolished a barn building on the property and saved some old beams from the trusses, etc.
I thought about cutting these, but my miter saw can't handle such thick beams, and it's also a very hard type of wood.
Can I buy a reciprocating saw blade to cut with?
Sometimes there might be nails in the beams that I can't see easily when cutting, which can damage a blade.
The question is, what tool should I use to most easily cut these hefty beams?
Without too much hassle.

A reciprocating saw with a good saw blade might be suitable. However, the precision with a reciprocating saw is not very good, but maybe that doesn't matter?

I'm going to cut them into 40 cm pieces and then split them with a wood splitter.
Use them for burning later
So the quality of the cut is insignificant
What size teeth should I have on the blade then
They are 19 cm thick beams, some are 25 by 25 cm

Buy some demolition blades of reasonable quality and you're all set. The remaining blades are excellent for cutting roots.

Sell on Blocket. They'll be picked up and you'll get money.

A reciprocating saw is a toy, maybe one or two cuts and then you're bored, for those coarse cuts you should use a chainsaw, available in both gas and battery.

Since there are nails in the studs, TS is likely to get bored sharpening the chain instead.

A good reciprocating saw with a coarse "demolition blade" works fine even if there are nails.
