Indeed, but practice has to start from somewhere. It isn't easy at first but not hard to learn. These cheap and low power grinders are a great start for a casual consumer. That is if he wants to learn, if not and money isn't an issue, he can just send his knives to people that do these services and pay $50-100 per knife.
I guess I mean regrinding the spine. Depending on how that goes I may take it a bit further.Evil D wrote: ↑Fri Mar 06, 2020 6:35 amDepends on what you mean by regrind. If you mean a full blade grind regrind, I have a knifemaker who does them for me. If you mean tweaking the shape of blades and regrinding the spine and such I do that myself usually with a Dremel and/or a mini bench grinder.
Thank you for the info! I’ve got a lot of older knives to practice on.emanuel wrote: ↑Fri Mar 06, 2020 9:12 amI use a small belt grinder, 1x30 belt 375w. Nothing fancy or expensive, just some German brand that had good reviews on Amazon, but if you're american it seems like the one made by Harbor Freight is very popular. You can find these made by different manufacturers and they're all in the range of 60 to 100 dollars. For small blades it's amazing. Some good quality ceramic belts and it will regrind even Maxamet or other ultra hard steels relatively quickly since there isn't that much material to be removed to begin with, so even this low power bee can do work.
Worth every penny imho, what I might add is to be careful for the first 5-10 regrinds, use it on some inexpensive, cheap pocket knives. You will make a few mistakes, biggest one being grinding the spine thinner, which you don't really want to do Also, cool your knife every few seconds, and don't be cheap on the belts. When they stop cutting properly, change them. Not only will this save up time, but also cut the steel instead of just burnishing and overheat the blade. This is even more important on very hard steels (63hrc and up). If you're still not convinced, 1-2 knives regrinded by a knifemaker cost as much as this entire setup...
If you really want to try this yourself, have a look at some youtube videos about it. Seeing how it's done will help way more than anything you'll find written anywhere and give you a mental foundation on how to start your trial.
Ha. I can definitely agree with you on the HF belt sander. It is fast and will pull a blade away from you quickly if you don't keep movements smooth and light. However it is also a workhorse. I've been using mine for the last 3 years or so and it always gets the job done. After learning on the HF sander, using variable speed tools is a breeze haha. I have been considering investing in a higher quality model at some point but my ol HF gets the job done every time so I've never seriously looked into upgrading.Nate wrote: ↑Fri Mar 06, 2020 5:18 pmI've had a 1x30 from Harbor Freight for a few years and would echo the other comments in general. I rigged up a simple drip line with a micro valve for fine adjustment. This low-tech water cooling has a lot of advantages.
While I've had a lot of success with it, the HF 1x30 is wicked fast and not very forgiving. Something different I've considered recently are the various angle grinder belt sander attachments on the market. With a variable speed grinder hooked up I could see this working well. However I'm a little concerned able the exact size(s) of the belts and the availability of high-quality ceramic belts in what may be odd sizes. If I can confirm a specific model uses the same belts as the WorkSharp belt sander attachment, I'd probably jump on it, but so far I haven't found much info on people using these for knifemaking or mods.
Here is one example of these attachments (not an endorsement):
