SCRAPERITE

Engineered Plastic Blades and Professional Holders

Scraperite invented the plastic razor blade and built its reputation on material science. Performance is determined by composition, not edge shape alone: pliability controls how the blade flexes on delicate versus stubborn surfaces, and chemical resistance determines which solvents it can safely tolerate without degrading. This guide helps you fit the right blade and holder to the job.

Material Families

Choose composition first, then pack size

GPO Orange: pliable and forgiving for delicate finishes and coated surfaces.

MBL Blue: balanced flex and wear for marine, pool, and curved surfaces.

BIN Black: higher solvent tolerance where stronger chemicals are part of the process.

PRO Magenta: tougher bite for demanding residue removal where higher pressure is required.

HYL Yellow: rigid profile for hard flat surfaces such as glass and tile.

Holder System Highlights

The holder is as critical as the blade

Easy Blade Change

Patent-pending release system makes flipping and replacing blades fast and controlled.

Corner Reach

Trimmed holder angle improves edge access into corners, seals, and frame recesses.

Dual Blade System

Tradesman Dwarf and SRT168 support both curved and rectangular blades in one holder.

Strengthened Body

Pre-stressed curve, added ribbing, and thicker structure improve leverage and torque.

Ergonomic Handling

Sloped palm geometry helps reduce fatigue during repeated or extended use.

Extra Reach

Longer handle options increase reach, pressure control, and job-site efficiency.

Tradesman Holder Family

Dwarf 63 mm, Standard 168 mm, Wide W410

Use the Dwarf for compact control, SRT168 for all-day reach and leverage, and W410 for broad-area productivity. Across the holder range, blade position is pushed outward and forward to maximize usable edge and access to difficult geometry.
