4" x 6"

Round ceramic honing rod with a black hex handle (the hex flat keeps it from rolling on the counter). Realigns and lightly refines an edge between sharpenings; gentler and finer than a grooved steel, so it works well on harder kitchen knives. Ceramic — will chip if dropped on a hard floor.

Two-stage pull-through manual sharpener with diamond abrasives, set up for Asian-style edges (roughly 15° per side). Stage 1 sharpens, stage 2 hones/polishes. No power needed. Good for quick touch-ups on Japanese-style kitchen knives. Used but in working condition.

Cheapie Rigol scope from Amazon. Comes with power cable, two probes, instructions, etc. Haven't used it in a few years so I'm a little rusty with driving it, but works well.

Titanium Easy Flux 125 from Harbor Freight. Light-duty welder for thin steel plate, welds are dirtier than MIG or TIG but doesn't require shielding gas and can be used outdoors on a windy day.
