Tabletop cutters?

[T.G]

Some tabletop cutters have a replaceable blade, some don't, most can be professionally sharpened if you can disassemble them (ie: not riveted construction). While I've never tried the following, I have heard some people claim success in deburring those with inaccessible blades by crumpling a sheet of aluminum foil into a tube and chopping it up with the cutter, not exactly sharpening, but it helped, or so they claimed.

Due to the small image size and lack of clarity, it's hard to tell what can be done with the cutter you posted.

If you like the idea of it as a decoration, just go for it regardless, especially if the price is reasonable, as generally speaking, decent tabletop cutters are not cheap.
