Very high quality. Very good for marking and as a knife to prevent tearing. Recommend this tool to anyone who needs a fine line marker and scale to prevent tearing. The fine micro adjuster works great, especially if you have a dial or digital caliper to set the cutting distance. Highly recommended. Would buy the same tool and brand if I ever needed a new one. Can be easily sharpened with a whetstone or fine wet or dry sandpaper. Very satisfied
