Bow saw blades. What are the different types?

[Handmade Matt]

I'm looking to buy some new blades for my bow saws and I want to show an interest in getting the correct types.

Some look like this:

And some look like this:

Is one for green and one for dry wood? Which is which? Does anyone know why?
Any more info would be great as well, I'm keen to learn.

now i dont know anything about them, but at a guess the bottom one would be better for green wood as it has the bigger spacings, allows less friction and more room to remove the wet dust....

will be good to know.....

The bottom one is used for green wood, it has raker teeth to clear out the waste green wood from the cut.

Yep Chris is on the money. Top one is called peg tooth and bottom peg and raker (or at least that is what those patterns were called on old hand sharpened cross cut saws) Peg and raker is a bit more efficient at clearing the dust out of deep cuts. The pegs cut either side of the groove then the raker chips it out. I guess peg tooth spreads the work over more cutting teeth so if the wood is a bit drier and less likely to clog then peg tooth may stay sharp marginally longer. In practice both work well and you won't go wrong. Just make sure you get the right length for your saw.

The bottom one is for green wood as it has the raker tooth which help in clearing the cut, while the top is for dry wood.

The blade for green wood can be used on dry wood and is ok, however not so good the other way round(dry wood baled on green wood).

Hope that helps

woop woop, hey i got somthing right....

My advice is to buy the second blade.(green wood)
I've tested them both on different kinds of wood. (dry- and green wood)
Greenwood blades perform better.

Please note that some suppliers may differ to the mounting holes.
In a conventional frame saw it's not a problem.
With a folding camp saw this can be a problem.
If you replace brand x for brand y it's possible that you can't fold the saw anymore.

Both manufacturers say that the blades are 36" (24"or 21") long, but the mounting holes may differ.

Brand x blade detail: oovvvvvvvvvoo
Brand y blade detail: oovvvvvvvvoo

This kind of saw gives no problems:

This kind of saw will give problems because the saw will not have a 90 degrees angle anymore.

It will be like this: \vvvvvv/ or this: /vvvvvv\
Hope you all understand what i try to explain.

If they were 24 or even 21 inch blades I'd half with you in a shot. 36 inch a bit long for any saws I've got.

Thanks Theo. My saw has multiple holes to bolt the blades into. I'm surprised most don't.
