Sharpening Jig for Bahco Scraper

I'm currently renovating my house which imply a lot of scraping of doors and wooden stairs... Therefore i use the Bahco scrapers which are really really nice ! Even if the blades stay sharp for a long time, it doesn't mean a resharpening doesn't help so I desgined this Jig to get the perfect angle of 20 degrees on my sharpening diamond stones. You can use M3 screws to secure the blades but it's already a tight fit (best is to slide them in instead of pushing from the top) and they are pretty much secured.
