Buying advice

When choosing lab knives and scalpels, prioritize blade material (carbon steel vs. stainless steel) for sharpness and corrosion resistance. Consider whether you need disposable for convenience or reusable for cost savings. For delicate work, spring scissors or diamond knives offer precision, but for general cutting, a standard #3 handle with carbon steel blades is versatile. Always match blade size to handle type (e.g., No. 3 handle fits #10, 11, 12, 15 blades).
