The Item Definition Indexes page is more for coding stuff which use the classnames and item definition indexes, so its names are human readable for that reason.

For a tournament list, you might be better off copying the names from an existing tournament config, or get the full list of names by running the item_show_whitelistable_definitions command on a TF2 client.

(con_logfile right before that command would be a good idea)

Edit: Here, I'll save you the trouble and just upload a copy I took from my server after using sv_cheats 1.

Edit 2: It's 'Stickybomb Jumper' in the whitelist.
