No Problem! 

With Sitemason's CMS, you can always recover a deleted tool by clicking on your main sitebuilder

(NOTE: This is done within the Old Site Manager - If using the New Site Manager, you must first switch to the old view)

Then about half way down on the "Setup and Information" tab, you can see a section that says "deleted pages" with a drop down menu. From Here, you can restore a tool/page that you had previously deleted by choosing it from the drop down menu and clicking "restore".
