The verbiage is different with different reports. In one for 20th of july it states: Just before their departure, pilots receive their short swords from Captain Ariizumi. Another article says: Each was presented with a Tokko short sword.
Another says: they were gifts sent by the 6th fleet commander and HANDED OUT, this is the quote: There was a solemn send-off ceremony on July 19 in Maizuru—a ceremony that had become an increasingly frequent routine in the Japanese navy and army air forces in the last days of the war, as pilots of Tokko Tai (Special Attack Corps) readied themselves for their final sortie. The 12 crewmen of the six Seirans were each presented with a dagger in an unlacquered wooden scabbard—a samurai warrior’s personal weapon that has not drawn blood—as a symbol of prayer for success in their last and highest mission of honor. The daggers were sent by the sixth fleet commander in chief and personally handed out by Ariizumi. These gifts expressed an unspoken expectation that each samurai would not hesitate to make the final dive of his aircraft and dash himself and his comrade into the enemy target to ensure the success of the mission in defense of the “ancestor’s land.” That these missions were tokko (special attack), called “kamikaze” by Westerners, was solemnly understood by the flight crew, the commanders, and the nation. It may not have been written in the order of the battle, but it was implicit in the prevailing doctrine of battle, the sacred ritual, and the mounting urgency of the homeland defense. For the first time in the kenkon itteki strategy that had produced the one-mission aircraft designed for maximum effect, the mission became a truly one-way tokko attack.

It may have been that terminologies from Japanese words to English did not translate the same, so ..Is it semantics, or interpretation, who can say, but the Imperial records might shed light on if the Tokko Sword/ or Dagger ,whichever you choose to think of it to be is another example of varied interpretation in itself.
There are writings of actual goodbye letters from kamikazis saved, some of which are available on my next link, the interested may shed light on the subject, but I have not read them yet.....too many, but here they are.

As I said the subject hasn't been fully investigated regarding the elusive sword end of this discussion,but,to me Japans records should be the final word...regarding IF the nature of blades like the ones submarine kamikazis had were both issued, presented, or what, but seems no one has asked yet to see the records,or find out what sword maker made them.
From my brief investigation, there were 12 "given"(we will say) out on the I-401, so a possible total of 36 for the I-400 class pilots may have been forged for these flying Samurai.
I respect all opinions on my humble observations. (More to come)
