Roman knife shapes

[Kegluneq]

Equally, why would you have utility knives in a kit?

Why wouldn't you? Kitchen knives are often sold in kits now and that's only the most obvious example. We don't know much about how other craftsmen (leatherworkers, butchers, tailors?) kept their tools together but I wouldn't be surprised if they used similar looking bundles.

Surely a surgical set for a field surgeon would be a marketable product.
You wouldn't want the most expensive surgical instruments being out on campaign,
where they could potentially be lost to the enemy.

You could say the same for any item of military equipment! I think if a surgeon is in a position to lose his instruments he's probably also going to lose rather a lot more as well - in that his camp, fort or marching column would have been overwhelmed... I think there's also the question of whether functional iron tools would be significantly cheaper than copper alloy to take into account.

They could just as easily be 4 moulded wooden columns supporting the shelves, with a square pull out drawer in each one. you can even see the drawer handles

The 'bundle' on the right does appear to have a ring pommel knife (or similar) in it, so I can't see them being just columns. That said, I have no idea what the 'drawers' might actually be if that were so.
