Hi,
On figtrees, I only use pruning sheers. There are some big sized and I have one of those too. They are for branches up to 3cm (1') of size.
There are some bigger for branches up to 5cm (almost 2'') .
To cut down other trees, I use a normal but new saw. You can replace the blade when it gets too hard and too long to do the job.
Changing the blade sometimes is a good advice.
There are blades for "dry wood" and some for "green wood". For trees that are alive, you want the blade for "green wood".
A new blade here is 5 bucks. The complete saw is 10 bucks (blade + good handle - you can get some cheaper with no hand protection).
How much is a "silky" ?
