Conclusion

There really isn’t a definitive answer to this question since there are so many variables involved in knife making (e. g. type of steel, hardness of steel, desired edge angle, etc. ). However, as a general statement, most knife makers use a belt grinder for the majority of their grinding tasks, including shaping the blade, beveling the edge, and even putting a fine edge on the blade.

Some knife makers also use a bench grinder for certain tasks, such as shaping the bolster area or the handle, but this is usually only done for custom or one-of-a-kind knives.
