Uchigatana Tsuka Lengths

[Salvatori Moretto]

Picked up a blade to mount for myself, labeled as an Uchigatana. Almost finished the habaki already and wanted to plan overall dimensions, and this is where i'm stumped.

Obviously a more petit blade, modern but made seemingly well. nothing spectacular honestly.

 

Here are blades overall stats from the purchase:  

Blade length（nagasa, 刃長, はちょう）: 68.4 cm
Bottom width (motohaba, 元幅,もとはば) : 2.8 cm
Top width(sakihaba, 先幅,さきはば) : 1.9 cm
Blade thickness(motokasane, 元重 ね) : 0.68 cm
Top thickness( sakikasane, 先重ね) : 0.5 cm
Curvature of the sword（sori, 反り）: 1.2 cm

Nakago (after i take away space needed for habaki) will only be 15.2cm or about 6 inches.

 

Usually when I carve out a new tsuka i like to limit the excess wood past the nakago to 1.5 inches to 3 inch's at absolute most. Now this is a general rule of thumb for me, but i was curious to see if anyone knew of standards for uchigatana vs katana in this matter? How much shorter, if at all, were uchigatana tsuka? Anyone want to chime in on what they feel a blade with these measurements should have tsuka wise? It's a modern blade, unsigned, most likely just a relatively nicer made blade from china with a more classical/traditionalish polish, so i also wouldn't mind shortening the blade length to give myself a slightly longer nakaago and redrilling the mekugi ana.

I've done 15/20 mounts but always on katana, and the measurements of this blade, specifically the short nakago, have me wondering about tsuka length for the first time in a long time.

 

Thanks for the input!!
