Oire-nomi or umeki-nomi for small sizes

I have both oire-nomi bench chisels and umecki-nomi dovetail chisels in various sizes. I'd like to add a 3mm chisel to my collection. For a chisel that small does it matter which style it is? I understand that a umeki-nomi is designed for lighter hammer strikes but you're not going to be wailing away on a chisel that small anyway so is there any advantage, one over the other?

Thanks

3mm chisel are very fragile they are easy to bend and care must be taken when setting them up. I would opt for Kaku-uchi oire-nomi with their boxy cross section they will make them more rigid.


However a Mukoumachi Nomi would be even better. Since they are taller then they are wide and have allot of rigidity.

I've got a set of 1.5-6mm chisels all were purchased as 'standard' nomi's but in smaller sizes as thumbsucker said, they basically come in the format of a sized down mukoumachi nomi (mortise chisel). I don't think i've ever taken a hammer to any of them. Just pushing pressure for detail / cleanup work. It takes a good smith to make accurate chisels under 3mm.
