Pair of 12" Carvers at the car boot this morning, priced at £25 each but he took £45 for the pair. The seller had them a few weeks ago but as I didn't need (want) any more 12" ones (preferring to acquire a couple more of the 6" size) I didn't buy them however today my resolve broke...
They've had some use but the springs are good, the seller was grateful that I knew what they are.
Continuing with the flow a Noco GB70 for £169 with the trade card discount from Halfords which I have been mulling over for some time.

Cheap because theoretically you get twice the life. In practice, as soon as you cut anything deeper than blade width, you'll destroy the other side...

I used to think that's what the blades of iron saws look like, because as a child I only knew this kind.
The saw gap will be larger than the material of the saw blade itself, because a) the cutting edge is corrugated and b) this happens easily when sawing by hand - so I'm not sure whether the rear cutting edge is really affected when going through the material ... I was too small at the time to be really interested in it.
But I remember that I was always amazed at how clean the cuts were that Grandpa made with it ... Well, that was his profession, he was a factory fitter in a steel mill - but he certainly wouldn't have used it if the back blade had ruined his clean cut right away ....

I don't think that one could ruin the other without leaving and getting marks ...

With these saw blades the teeth are not set as here
but the whole cutting edge is wave-shaped, which can also ensure the chip removal.
These saw blades have no teeth pointing outwards.
I don't see how the back cutting edge could be damaged: the cut has the correct width and the saw teeth only point backwards ...
Wiki:
"To prevent the saw blade from jamming in the material, it is designed in such a way that the generated saw slot is wider than the saw blade; the saw blade thus cuts itself freely and does not jam in the material, this is called free cutting. There are three different types of saw blades for this purpose:
- Waved saw blade: the saw teeth run in slight curves (waves).
- Compressed saw blade: The saw teeth are slightly wider at the tips.
- Set saw blade: The saw teeth are bent alternately to the left and right."
So, during the second material pass, set and compressed saw blades would actually be damaged, but wavy ones would not ...
... but what do I know, it was decades ago, probably you are right

The thing is, as you use it, the teeth wear so the clearance reduces. Also, you're pulling the saw backwards and forwards, so the top blade will be trying to cut one way or another. I think there's a reason we don't see them anymore, and when we went into detail about hacksaws in college (yes really!) In 1977, they were comprehensively written off...

Thanks!
So, you knew this kind of saw blades?!?
Then it's maybe not a regional or national thing, but a thing of the times now and then: perhaps it made sense once to save material but didn't stood the test of time.
Right, it was not so easy to find new offers for such saw blades and if, preferably for PVC pipes.
So that was just what there was in our household when I was a kid, as a tool it has not generally proven. Ok.

That’s different then
Carvers are always hard to come by at sensible money.

Combination of reds and we're having problems with boar at my Nan's.
People said just get a 308 trouble was it was too "similar" to the 243. 243 is perfect for down here in Wales for foxing etc., (very high velocity thus flat trajectory). 308 is too big for stuff down here and up in Scotland not enough (for me) of a differentiator to the 243. The 300WM is basically a supersized 243, I.e. it's still chucking rounds down range at 3000+fps just that it's throwing 150gr rounds rather than 56gr.
I must admit until today I didn't realise how similar the 338 lapua was in case size...
