among some of the other stuff my grandfather brought back from the pacific in WWII are these three knife/bayonets, the one in the center I know is a type 30 bayonet but the 2 above and below it I have no idea but I don't think they are bayonets since they lack the lug attachment point. I thought they might be trainers but every trainer iv see has the lug attachment point.

there is one thing I do know about them, the ones above and below the type 30 bayonet don't have the same length tang. the type 30's tang is 4 1/8 inch.
the top one is 4 5/8 inch and the bottom one is 3 1/2 inch.

has anyone seen any of these before or know what they are?

I don't recall ever seeing anything like them before.
But you really need better photos then #2 & #3 for anyone to tell anything!

Perhaps from the apparent crudeness, they were "Last Ditch" expedients for the final battle of the Japan homeland invasion that never came??

csa,

The top and bottom blades are called 'pole bayonets'.

They are considered pretty uncommon and do have a definite value to the advanced collector, especially the third blade with the really nice box scabbard.

Meant to be tied onto a pole through the use of the top and bottom holes on the crosspiece to form a pike of sorts.
These were used to varied effect during the night 'Bonzai' charges. Blades do not run out of ammo and the night actions often became a close quarters contest.

The second photo shows the Jinsen Arsenal star (Jinsen is the Japanese word for the city of Inchon, Korea where the arsenal was located). That Arsenal marking has been identified on other pole blades as well.
I do not recognize the spine marking in the third photo.

Natural light photos with ricasso and spine markings - if present - on all three blades would be great.

Pole bayonets do not often come up for sale and they look to be in good shape with unground edges - a definite plus.
That is to say, all three would sell with contending multiple bidders should you put them up for sale.
I would be one of them, but also sure to be outbid!

Thanks for sharing some fairly rare blades with us.
