Is the Brvclon bread slicer worth it for home bakers?

How the brvclon bread slicer's crank and guide actually work

Here's what actually happens when you turn the crank. The loaf sits inside a solid wood frame, held to the counter by suction cups underneath so the whole thing doesn't creep with every push. A stainless steel blade rides along a metal guide track set at whatever thickness you've dialed on the scale line, anywhere from a hair's width up to just under an inch. Turn the crank, the blade travels straight across, and it comes out the other side at exactly the thickness you set, not whatever a serrated knife happens to feel like giving you that day. That fixed guide is the bit worth understanding. A knife wanders because your arm wanders; this doesn't, because the blade never leaves its track. Set it to a thin mark for sandwich bread and every slice after the first one matches it, all the way down the loaf. Set it thicker for toast and the same thing holds. For a soft-crusted country loaf that flops under a serrated blade, that repeatability is the whole appeal, since the guide does the holding-straight your hand can't reliably do by slice fourteen. The blade itself is removable, which matters more than it sounds like it should: a bread blade dulls, and being able to swap it instead of replacing the whole slicer is the difference between a kitchen tool and a kitchen ornament. It's hand wash only, so it's not going in with the rest of the dishes, but that's a small trade for a blade you can actually replace.
