Just a small saw from a pumpkin carving kit.
In all fairness it is a synthetic pumpkin which doesn't nessisarily make it easier to carve because its not as soft but it does allow me to feel like I'm not an idiot who spent 8 hours on something just to watch it rot away in a few days.
The trick with real pumpkins is to scrape them until you have a thin outside shell. If you only scrape the guts out the thing is too thick to get any minor details.
Bonus, this one might have earned me a visit ot Lake Ronix! Totally worth the effort.
