This durable tool will give you years of service. A razor blade is too wide to use across the top or up most A-pillars, but it is ideal to use across the bottom. The nice thing about this tool is that you pull out the old blade, put a new one in and you are ready to go again, no sharpening needed. Comes with a safety cover that keeps the blade sharp and prevents the technicians from cutting themselves when this tool is in the toolbox.
