[Case Study on Problem Solving] Blades that have been re-sharpened multiple times feel a strain.
We address the issue with revival processing that restores the width of the shinogi to its original width when new! Here are some case studies that solve your problems.
We would like to introduce a case study that addresses the customer's concern: "Using a blade that has been re-sharpened multiple times results in feeling a load during cutting." When re-sharpening is done repeatedly, the bevel shortens and the cutting edge becomes thicker, leading to increased side pressure and a corresponding load during cutting. In response, our company implemented a revival process to restore the bevel width to its original size. 【Revival Details】 ■ Blade Inspection (chipping, rust, cracks, etc.) ■ Blade Correction (warping, twisting, etc.) ■ Bevel Processing (restoring to the original length) ■ Edge Sharpening (sharpening at the original angle) ■ Safe Packaging *For more details, please download the PDF or feel free to contact us.

Company information
At Shinwa Kijin, when receiving orders, we listen to customers' requests regarding the cutting work, cutting methods, and processing. Based on our 50 years of manufacturing experience, we provide advice and select the material, taper angle, and cutting edge angle of the circular knives. By maintaining a consistent production process, we offer products that meet our customers' needs. Additionally, while Shinwa Kijin is a manufacturing company, we also focus on regrinding. Regrinding is not just about ensuring the blade is sharp. To ensure safe use, we conduct visual inspections of the blades (for chipping, cracks, etc.). Once the inspection is passed, we proceed with the regrinding. Since we select the cutting edge based on the cutting work and methods during manufacturing, we must grind the cutting edge to match the specified angles. Furthermore, for products that have been regrinded multiple times, we also need to perform taper processing. By paying attention to these aspects during regrinding, we can restore the original sharpness of the blades.
