Although not a limited or special edition/issue - the Mcusta 183D "Ieyasu" is still a fairly rare find.
The 183D is in the Mcusta "Sengoku Busho Series" - laser engraved on the handle "Bushido- Tokugawa" -
Ieyasu (家康


There are listings by vendors misspelled as "Leyasu" (I assume because they can't believe the spelling is "Iey..." )
The handle is brown/black "Staminawood" (a variant of Pakkawood - ie: epoxy laminated hardwoods - it ought to be as practical and resilient as Micarta - but with the looks of wood)
The handle is designed after Samurai "Yoroi" armor
The 183D is a larger Mcusta -
it has the same 3 3/4" blade as their Tactility series
which is larger than the MC1- & 2- basic series (3 1/4" blades)

Top to bottom: 74D "Take" (2 3/4" blade, cocobolo); 16D Basic (quince-wood); 124D "Tactility" (quince-wood); 183D "Ieyasu"
Size compared to a standard SAK (Swiss Army Knife) -

Blade details -


The suffix "D" means this is a "Damascus" blade - it is not "true" Damascus -
but vg10 core with patterned layered nickel/steel cladding.

Edge -


Mechanically this sample is a bit stiffer, even though I have adjusted the pivot tension - the action is still very smooth - but there seems to be a bit of inertia to overcome.
The liner lock-up is good -

although again the liner seems to bite a bit, so sometimes it's harder to unlock - when I first got it the liner-lock wore a groove in my thumbnail.
Everything is nicely lined up -

Unlike the smaller Mcustas - this (and the Tactility series) use a conventional stop pin in the handle - as opposed to using the thumb-studs against the handle end to stop the blade.

not quite perfect - but blade still pretty nicely centered in the handle.
Attention to detail -
pouch is nylon with leather -
leather is more than just decorative trimming -
but extends to the back of the pouch to form the belt loop -

The closure is by a pretty heavy duty snap fastener.

I was initially concerned that the back of the snap would eventually mark the handle as it needs a firm press to snap close -
but closer examination shows that there is a soft plastic guard on the back of the snap -

.... nevertheless I think I would still have preferred Velcro closure, to avoid any issues with pressure against the handle.
