KC Tools sells a set of Wera brand tools that they’ve assembled into what they are calling the Knife Maker and Maintenance Kit. It includes 7 Torx drivers, a small rack for storing them, and a small 1/4” bit driver with 6 Torx bits.
Wera tools are German designed and Czech made and in my opinion are every bit as good if not better than Wiha. It’s a great set of all the sizes you need, at a decent price.
No affiliation, just an appreciator. I’m still new here, so I’m a little fuzzy about the rules, so I’m not including a link or picture. I can edit to include either of someone can confirm that that’s ok.
Another valuable tool for knife maintenance is a set of (cheap is ok) dental probes, and some disposable dental brush picks. Not a standard toothbrush, dental brush picks resemble very tiny bottle brushes. Good for getting into crevices.
