Blade vs Burr: Which Grinder for Coffee & Spices?
Blade grinders chop with a spinning blade, fast and versatile for spices, herbs, nuts and drip coffee. Burr grinders crush between two burrs for a very even, adjustable grind that matters most for espresso and pour-over. Most spice-and-coffee grinders are blade grinders.

Why blade grinders suit spices
Spices, herbs and nuts do not need the microscopic evenness that espresso demands, and they vary hugely in hardness and oil content. A blade grinder's chopping action handles all of them, and pulsing lets you stop at a coarse crack or push to a fine powder. That versatility, plus a low price and easy cleaning if the bowl is removable, is why blade grinders dominate the spice-and-coffee category.
Why coffee sometimes wants a burr
Coffee extracts best when the grounds are an even size. A blade grinder produces a mix of fine dust and coarse chunks, which is fine for drip coffee but can make espresso and pour-over taste unbalanced. A burr grinder crushes beans to a consistent, adjustable size, which is why serious coffee drinkers use one. For most people who mainly grind spices and make drip coffee, a blade grinder is enough; for dedicated espresso, a burr grinder is the upgrade.
