Best Jointer Knives

Summary

If you're dealing with plenty of wood day in and day out, or perhaps you're just a dedicated but casual woodworker, then you know the importance of having trusty jointer knives for your wood jointer. The machine allows you to cut pieces of wood of the same size. This notion is important in the creation of individual wooden items, such as furniture.

If a jointer knife doesn't get the job done right, then chances are one block of wood won't be aligned with the other. Therefore, the furniture will either be lopsided or perhaps it's deemed unsafe to be used.

As such, never underestimate the power of the best jointer knives that money can buy. These knives won't put a huge dent in your wallet, but a sharp and reliable set can help you with many of your woodworking projects. It is even vital if you use your wood jointer on a daily basis as it might be your profession.

If you find it difficult to search for an accomplished set of knives, then you can fret no longer as the information you seek can be consulted by this guide we've prepared for you.

Introduction

I make furniture on a daily basis as a professional woodworker, and I rely on my wood jointer a lot. It is because it allows me to cut the necessary pieces with precision. Without a set of good jointer knives at my disposal, I couldn't get on a single task for a day. However, I did notice that the pieces I cut to connect to other blocks of wood sometimes leave me with more work than I originally anticipated. When I searched for the origin of the problem, I found my knives were either chipped or dull.

It should not be this way as I've just purchased them not too long ago. However, after a thorough understanding of the situation, I did buy the knives from a no-name brand, but they were cheap. Well, I guess I get what I paid for, but I decided to search for other knives that were above the cut (no pun intended).

It was then a woodworking friend decided to recommend me a set of knives that he uses all the time. These came from a well-known brand, and although they were slightly more expensive than what I would usually get, they did manage to help me with my daily tasks.

I just wished that I wasn't so cheap in purchasing high-quality jointer knives as it would've saved me time and effort.
