I personally have 100% completion and only fell below half my available shards a couple of times. I probably still have most of my shard consumables to restore them when you get low if I had to guess. I used the fire tool a fair bit late game, and the boomerang early game for a couple of fights, but presumably since I was using a crest with only one tool slot I consumed shards slower than the average joe.
Your basically not even out of the tutorial yet in the grand scheme of things.
Shards didn’t become a problem for me for example till well past the half way point.
