Hi,
A common modification for tired hands is the addition of a strong magnet, see
Edge Pro: What size/strength magnet(s)?
Thats about $10 worth of magnets
Keep in mind that magnet strength drops off a cliff as you get any separation distance beyond zero.
To give you an idea based on readily available magnets, I bought 2 packages of these (3 per pack) from Home depot:

I stacked 3 of them, and used a scrap piece of .475" thick baltic birch plywood that was 3" wide by 8" long (roughly the size of the EP Pro base).
I used a 3/4" forstner bit to drill holes .355" deep (the thickness of the stack of 3 magnets), which leaves .120" of wood (about 1/8") between the magnets and the knife.
Next I put the two stacks of 3 magnets into each of the 2 holes (spaced ~2" apart, center to center) and taped them so they'd stay in place when I flip the plywood over.
Even with the ~1/8" separation between the magnet and the knife, this held my heaviest kitchen knife (a Wusthof 4682/16 cleaver, ~25 yrs old) easily.
Square magnets would be better for small/narrow pocket knives since you have better magnet strength at the front edge compared to a circular magnet. With circular magnets and a small/narrow blade, the magnets will pull the knife to the middle of the magnet. Since you need the blade edge to overhang the EP base at the front, that doesn't work. But for larger width knives, it works fine.
Edit: here's a drawing, roughly to scale. I drilled 3 holes in the scrap base so I could also use 3 stacks of 2 magnets, instead of 2 stacks of 3 at the edges.
