The sword hanging on the wall is presumably Val’s proper sword, while the machete is just for informal greetings.  By the way the Machete has val’s name enscribed on it in Tolkiens Tengwar (that’s elvish to you if you don’t know what the Tengwar are [yes I am a nerd thanks for noticing]). I enjoy different alphabets, and you can be pretty sure that in the course of this comic there will be at least some Tolkienish Elvish, Anglo-Saxon Furthark, maybe some Cuneform, Greek, Cyrillic, and the odd Heiroglyphs.
