VEVOR Manual Pole Saw, 7.3-27 ft Extendable Tree Pruner, Sharp Steel Blade High Branches Trimming, Manual Branch Trimmer with Lightweight 8 Fiberglass Handles, for Pruning Palms and Shrubs

It's a double pully, the pully seems to be a very hard plastic, the housing and arm are metal. I've not had any problems with rope slipping off pully.

It doesn't have a pulley,or rope the way the blade is made, when you get it positioned were you want to cut you give it one good pull down and it bites into the wood really well the front of the blade keeps it hooked into the limb,

The pulleys are some type of plastic or polymer. I have had some issue with the rope getting off track or tangled in the branches but I'm sure anyone with half a brain would expect these types of things.

Yes why not

Yes you can order blades but it does come with one extra blade

It comes with 2 two

I did not use the pruner part but I would recommend using the saw part for anything over 1/2 in as it does get flimsy and pulling the cord with higher force will make it more awkward. Remember the hooks of the saw part are somehow sharp and can help doing a cleaner cut on the bark around the branch.

I dont know. Nowhere in the description does it say. My guess is 2 inches

I don't have the pruner option. I have seen videos on u-tube that shows this saw that has the pruner, but I didn't focus on it. You might try their website also.

Too be safe 3/4” branch,case it comes down at you

I have only used this tool for sawing; however, given the quality of all the components, with reasonable strength and sharp blades, you could probably prune up to 1" branches.

I've only used the regular saw blade, but think the pruner probably wouldn't cut a branch that was more than 2" thick. Also, the more you extend the pole the more unstable and shaky the blade becomes, so you have to consider that. The saw blade itself is very thin and wobbles, not easy to cut with. So I'm guessing the pruner is similar.

The tool I bought only has a saw.
