The Curved Edge Revolution: Why Woodworkers Are Ditching Sandpaper
When master carpenter Elias Thorne nearly scrapped a $4,200 walnut live-edge table due to jagged edges, his 3/8" roundover bit saved the project. In Fine Woodworking’s 2023 survey, 89% of pros reported achieving smoother contours with specialized roundover bits versus sanding blocks. These profile-cutting miracles transform:
- 🪵 Rough-cut lumber → Glass-smooth arcs
- ⚡ Production time → Cut routing stages by 70%
- 💸 Material waste → Save 18% hardwood costs
