This is an, in my opinion, improved version of the [Astra Razor Blade Holder](http://www.thingiverse.com/thing:2024019) by [miquelmartin](http://www.thingiverse.com/miquelmartin/about). I imported the design into Sketchup and cleaned up the mesh, and have included the .skp. Modifications include the following: - Lengthened handle - Larger diameter pegs for blade retention to improve blade stability - Shortened pegs for blade retention to improve clip rigidity - Added bevel to front bottom edge of blade support to allow for slightly lower angle of approach - Moved area behind rear of mounted blade forward to support blade when flexing - Added bevel to area behind rear of blade to improve clip retention and reduce possibility for exposure to rear of blade - Completely re-designed clip to provide better clip retention, improve blade stability, and ease insertion and removal of clip
