Hello Hans.. In the USA, Dewalt and others make "Sawzall" blades in what they call
"demolition" quality, which is supposed to be able to cut thru the occasional
nail without undue damage. They hold up to the silica in Bamboo quite
well, and are available in various teeth per inch:: of course the finer the
teeth, the smoother the cut, in most cases.
I often use the Metal cutting blades, which make a VERY smooth
cut, and are of even harder steel, as we use them to cut culms at ground
level, which means cutting into a bit to dirt, grit and sand occasionally..
Which of course is EXTREMELY hard on any saw blades. I buy them in
the very coarsest 'teeth per inch" I can find, which I believe is about 14
tpi.. A bit of a fine cut for mass cutting, and thus a bit slower, but
they DO hold up for extended periods of time.. Plus we only cut a few
poles at any one given time, so it's no big deal..
I would expect the "demolition " blades to be more what you might
like.. At least 3 or 4 different companies make and market them here,
and even they are of varying quality... (life in the dirt ? ? ?).. Most of
them probably come out of China anyway..
At the "Big box Stores" we pay around $3:50 to $5.00US per
blade in packs of 5 or so.. I have NO idea how that stacks up to the price
of your Sutton Tool Blades, but I DO know that the better German quality
tools and blades are quite dear in the USA... They DO have the quality,
but I don't think it to be worth it either, when we arecutting into bamboo
silica, dirt and sand:: a real 'torture test" for any cutting tool..
We also cut out chunks of rhizome from Clumpers, with the
Demolition blades, so that one is cutting directly straight down into the
soil.. One 12 inch blade makes about one good clump cut. 2-3--4 rhizomes,
depending on the size of the bamboo. Of course the huge, large
tropicals, WE don't have, so THAT is a whole nother issue.. grins and not too
funny..
Grace, peace and love to all. Kinder in Central TExas..

I have a 18v Hitachi reciprocating saw which is my favourite tool for
cutting bamboo, both culms and rhizome divisions. I have been using an
excellent blade on green culms. It is imported from Germany by Sutton Tools
Australia. They sell it under their own brand name with product code 4045.
It has teeth very similar to the better quality pruning saws. It makes a
very nice smooth cut compared to other reciprocating saw blades I have in
my
collection. The only problem is they are hugely expensive and I don't
understand why, I am looking for a cheaper alternative. I am sure many of
you are also using reciprocating saws, also known as Sawzall or Sabre saws.
Does anyone have a recommendations for blades for smooth cutting of green
bamboo culms? I haven't tried greenwood pruning blades yet, they are much
cheaper but with only 5 teeth per inch, they seem way too course to produce
a nice cut.
