Also the type of the key matters for tendonitis. Some have tactile feedback after the key is pressed but well above the bottom so you learn not to bottom out with force.

(They used to have low-force options; perhaps all are low-force now?)

Kinesis also offers custom switch options through Upgrade Keyboards: https://upgradekeyboards.com/collections/kinesis-advantage36...

Lead times are long, and Kinesis products are expensive. It gets a little more bearable if you take into account that you're using this tool 8 hours a day for years and years, but still. Cheaper options exist.
