What was even the curse about? So far the only significant side effect of the curse was a reduction in the agility stat while giving Def Pen and boosting all the other stats, and the most common curse was only being unable to take it off, and as a side character said in the early chapters, if the cursed equipment is comparable or even better than literally national-level artifacts (with the angel shield and the ring being an example), you could just live with it always on.
It's like the word 'cursed' is so taboo that they don't even try to listen what the curse was, when in Guile's tools case would almost always be a trivial side effect.
And don't downplay him as being 'somewhat remarkable' when typical magic items (as Maura said in previous chapters) can at most boost stats only 10% and only hold 1 enchantment, while Gaile's sword can enhance a stat to a whopping 150%, while having additional enchantments on top. Not to mention he literally created this thing in a day.
