I made a video tutorial on how to take apart and sharpen the T blade for my Wahl lithium ion cordless trimmers. I will be uploading it on YouTube tomorrow.. It worked great now to see if I can get the attachments to go on the bigger T blade that's available for the Wahl detailers so I can have that blade for my trimmers too. I also just sharpened my Wahl T-pros which are the cheaper version of the Wahl detailers and now that I did that they cut 10 times better and that's no lie!!!!
