I have a petrol hand held saw, but would prefer to hire a mechanical pressure cutter. These are OK with concrete block paving, but I haven't laid these 'cobbles' before; Link https://www.rock-unique.com/natural....es.html

They are basalt precision cut and tumbled 50 x 100 x 80 - 180 mm

I have a number of curves on the job so anticipating cuts as these are supplied as a random size/qty crate.

Anyone used/cut these?

I keep telling Chris at RU that they are Setts, not cobbles, but he sticks with the name bacuse that's how the ignoramuses of Kent refer to them.

I worked with thos ebasalt setts when RU first started bringing them in to Britain 15 years or more ago. They can be cut with a hand-held saw, using a stone-cutting blade, but best results will come from a bench saw fitted with a water-cooled stone-cutting blade.

When you refer to a "mechanical pressure cutter" do you mean a splitter/guillotine?

....these will work with the basalt setts, but that stone is pretty tough, so you would needs a splitter with a decent extension lever or, better still, one featuring a hydraulic jack (as shown on the page mentioned above) to generate sufficient pressure to split the stone.

And it will need to have truly keen blades - dull blades will severely hinder accurate cutting.

Tony, thanks for this. Great job of work this website and forum.

Hiring is not straight forward atm around here - will see if I can test the splitter (that is what I mean't) on one before hiring
