What Scraper Uses OLFA BTB-1 Blades?
The BTB-1 fits the OLFA BTC-1 and BTC-1/DX Multi-Purpose Scrapers. It is not interchangeable with standard utility knife blades — always match BTB-1 blades to BTC-series scrapers.
Blade Installation and Rotation
Install by opening the scraper's blade compartment and seating the 43mm blade per the tool's loading guide. When the sharp edge dulls, rotate the blade 180 degrees for a fresh edge; when the blunt edge wears, flip or replace. Dual-edge design doubles working life per blade.
Edge Configuration: One blunt edge, one sharp edge
Seller: Cutter's Bench

Perfect replacement blades
Fits my BTC-1 scraper perfectly and the dual-edge design is clever — blunt side for scraping paint without gouging, sharp side when I need to slice through old caulk. These cleaned 20-year-old adhesive off my garage floor. Steel is clearly a cut above the generic blades I tried before.

Good blades, wish they came sharper
The sharp edge is fine but needed a couple passes on my strop to get hair-popping sharp. The blunt edge works exactly as intended for scraper work on glass without scratching. For $6.49 for three, hard to complain.

Okay but rust if not careful
They cut and scrape well, but I left them in the scraper for a couple of damp weeks in the shed and both blades showed light rust spots. Keep them dry and oiled and you'll be fine. Performance itself is solid.

Sharp, tough, and the blunt edge saves my glass surfaces.
