That would be what we call around here a "Null-Nade"... it is the result of a misspelling of the items tag.
Example:
giveitem g_w_blstrrfl001 will give you a blaster rifle... but if you misspell the items tag (the second g_w_blstrrfl001 part of the code) you get a blank grenade.
To find a list of the items look
here (For K1) and
here (For TSL). The items code is the part in the title surrounded by parenthesis, sans the
.uti part.
I hope this helps.
