Tips about hand-cut rasps

1. How many rasps should I have ?

Beginners often ask me this question ; this means they have never used a good rasp. Then I always advise them to get just one, maximum two. This allows them to discover that they quickly use their new tool in many more cases than they had originally imagined, simply because they didn’t knew what a real rasp could do. Afterwards, the choice of the additional rasps is then easy, naturally matching their needs, and accorded to how their way of woodworking has progressed through the first rasp.

2. Can you give me a discount if I order more ?

No sorry. First, because I’m not going faster in producing more, unlike a production made by machines. Then, because I have anyway a limited production capacity. Also because I’ve never heard a new customer coming back and telling me that he found the price was excessive. And lastly but maybe the only good reason is because the price just reflect the time I spend on each rasp… and hopefully the pleasure you will take in using it. 😉

3. How to clean and maintain my rasps ?

The best solution is to regularly use a brass brush. From time to time, before storing it in the hard case which is provided with the tool, it is always useful to oil it to protect it from rust, especially if you do not intend to use it for a long period of time. To wrap – each individually – in a oiled rag is also fine.
Contrary to what I often hear, do NOT bathe it in acid! Sure acid attacks first the chips of all kinds that has remained at the bottom of the teeth. But even the hardened steel of the teeth risk to be attacked if failing to fully control the process! The edges of the teeth will be the first areas to suffer because they are by definition areas with the most contact surface with the acid, while having the least thickness of material


4. How do I choose the stitching grain of my rasp ?

Please first refer to this grain chart. If you have never used one of my rasps, keep in mind that their teeth are much sharper than those of mass-produced rasps. So to get an equal bite, choose a finer grain, and you will gain a lot on the smoothness of the obtained surface.

If you already have a rasp and wish to have another one of the same shape but different grain, I advise you to choose a gap of three grain numbers between them (for example, two Cabinet Makers rasps 10″, if your rasps is a #10, then choose the other one with a grain #7 for more roughing works, or #13 for finishing works).

5. How long does it takes to learn to hand-stitch a rasp ?

To date, I have trained eight people in my life. 3 have not succeeded, the other 5 have took between 12 and 18 months of learning and daily training before their first perfect rasp. Two are now retired, the other three are working with me.

6. Why your rasps are made for right-handed or left-handed persons ?

Because this slight orientation of teeth depending on the user’s hand greatly increases two essential qualities of the rasp : its bite and its ability to remove chips.
