A less expensive coffee grinder which uses a blade to grind the coffee. Inside it will look like a mini-blender. You can’t get the most accurate grind using this type of grinder as there are not any settings. You just put your coffee in the blade grinder and press the grind button. The longet you grind the coffee, the finer the grind. For those that use an auto drip coffee maker, this kind is probably the best value. A photo of the blade grinder is below.
