Any one have any idea if blade replacement is possible. I have toted this knife probably 20K miles. I thought it would be easy to have the company repair, never researched the company before, seems they are no longer. This thing is so easy to sharpen and holds an edge like crazy. I dropped it off 20 foot ladder on cement and the blade went one way and the handle another. I have other knives and will eventually find another Imperial but I am just sentimental about this one. Any suggestions on blade replacement. Thanks.
