We use refillables for a few printers. Cobra ink stuff. Uses bottles and a little funnel. Syringes for flushing are blunt, but we have a sharps for purging air in our dtg carts when they are new.
Can't get too upset when it's the tool for the job.
We have embroidery, sewing and carbide cutters for everything and anything, so basic sharps handling should be used in a work enviornment.
