Guild Wars 2

I would like to know if gathering tools get used up even if the gathered materials are ‘ruined’ due to using inadequate tools.

also, does each tool gather 1 resource at most? ex. 100 stack axe always gathers 100 logs.

Yes.
To my knowledge yes.

1. Yes, your tools lose a use every time they are used, including times when they fail to harvest due to quality of the node.

2. Each tool use is guaranteed to recover 1 item (either a resource or a ruined item). When a resource is gathered, there is a chance for bonus items depending on the type of node. Trees, for example, will sometimes give you an extra log or a “hidden stash” item that can be opened for loot. Mining nodes will occasionally drop gemstones. Plants will drop extra multiples of the ingredient, and occasionally a useless dandelion. These bonus items do not use an extra tool use.

Getting ruined items from gathering (assuming you are not using the wrong one) isn’t really related to the tools. It has to do with certain traits that get activated when you are attacked.

The infinite tools are no special in any way except for the infinite use. Any problem you can run into with Orichalcum tools you can still run into with the infinite tools.

Also no you can get more than 100 logs from 100 stack of axes/picks. Sometimes you get more than in a single swing of the axe/pick. Most likely due to WvW bonuses but there are also guild/banner/gathering boosters.

You didn’t ask this but you can still get the extra stuff from mining/chopping even if you end up with ruined items. The extras like the gemstones from mining and the hidden bags from trees.
