Nicks from a dull razor
Dear Daniel, My question is…
Why is a dull razor more likely to cause a nick than a sharp one?
You'd think the opposite would be the case!
Daniel Rouah Answers
Routine shaving doesn't dull the blade. The blades' microthin edge becomes distorted and this distortion of the sharp blade causes the nicks.
This is why an old-fashioned straight razor can be "sharpened" with a leather strop.
In fact the strop is smoothing - not sharpening - the blade.

Customer Testimonials
I ordered the Tangle Teezer in purple last week and am so impressed with it that I've just ordered another one for my niece for christmas in pink! It's brilliant and it was delivered so quickly. I love the touch of including sweets too, it made me smile - thanks!
I'm also going to mention it to my friends, I think a couple of them may buy it too!
Thanks again, great invention!
Kind Regards, Tanya, Bristol
I placed an order for 2 tangle teezers but only 1 arrived, I contacted you and was really impressed with the customer service who sent me my second one straight away, I was a little sceptical about it working so well but having now used it I can honestly say it really works! I find it refreshing to find something that lives up to its name as the Tangle Teezer does and will be telling everyone I know. Thank you, Joanie
I saw your Tangle Teezer on Dragon's Den and decided to try it as I have very fine long hair. Every week my hairdresser backcombs it and puts it up for me - the only way to get body and height. When I come to take it down it is a very difficult job to disentangle it. What a difference Tangle Teezer has made. Thank you. I shall buy them as Christmas presents for my daughters and granddaughters! Thank you. Christine, Colchester
