Quick Navigation
What Kind of Power Type Sharpeners Use?
There are two types of sharpeners, electric and manual, in terms of their power.
The first difference in the power source is obvious; however, you might want to consider some additional features.
For instance, a manual sharpener is cheaper, but it requires hand labor to properly sharpen the blades. On the other hand, electrically powered sharpeners offer more efficient use without hand straining, and they’re usually a bit more expensive.
Whatever you choose depends on how often you use it and what type of blades you need to sharpen. We think that any option can help you sharpen the blades and improve your lawn mower’s performance.
How to Ensure Blade & Sharpener Compatibility?
Different lawn mowers use different types and sizes of blades, so you must make sure they’re compatible. Ideally, you can use them for different types of blades, not just one type.
Remember to check the blade size and angle. The perfect sharpener must fit these numbers.
What about Durability?
The durability of the sharpener depends on the material it is made of because it lowers the risk of damage and potential injuries. The ideal solution is to purchase a sharpener constructed with carbide or one with good warranty options that can ensure the long term.
How Important is The Spinning Speed?
When purchasing a lawn mower blade sharpener, you can check its spinning speed to get a better idea of its performance. To check this, look for the RPM abbreviation since this number refers to the rounds per minute.
The higher the spinning speed number, the better the performance. The RPM options can vary from 1500 RPMs to 1750 RPMs. A good spinning speed can offer smoother sharpening and improved mower performance.
How to Stay Safe?
Safety comes first when working with any gardening tool, but this is especially important for lawn mowers, blades, and sharpeners.
When handling lawn mower blades, remember to wear protective gloves and always remove the spark plug. If you don’t, you risk injury and even breaking your hand.
These are important steps to follow when changing the blade and when sharpening it. Always wear protective gloves and be careful when handling blades.
Additionally, it’s important to understand whether the blade is good for sharpening or needs a replacement.
Some blades are just done after years of use and need to be replaced, so if you try sharpening them, you won’t get the desired result, and you might think that it’s the sharpener’s fault; however, this isn’t the case.
When it comes to the actual process of sharpening, make sure you start from the top side of the cutting edge—this ensures a long-lasting edge on the blade.
