Cordless electric shaver blade sharpening

[Slinger]

No, it is not another sharpening thread, but has anyone ever tried to sharpen the circular blades on a Philips Shaver model P/T 720. The razor cost new £45 some 2 years ago & it is recommended a blade/new head change after every 2 years, but the price is some £30 which at 66% of the original purchase price appears to be very excessive. I know there are some tips on the web, but I would prefer advice from someone who has actually done the sharpening. I have always found Philips to be an excellent manufacture, but the consumable price of a new head seems out of kilter with the original purchase price. No, after some 40 years of having a full beard, I can no longer do a wet shave (more's the pity). Cheers & a Happy & Healthy New Year to all our 'readers'.

Can't wet shave either :-(

I have a couple of the Philips cheap AA-celled ones. I think they are designed so that one blade abrades on the other (rotor against the outer slotted ring). There's no doubt the rotors on mine have an attack angle, but I think the 'frog angle' is the same as the bevel.

You ( well, I) might try just moving the rotor around gently in circles on a fine grade bit of wet+dry stuck to glass or MDF, similar to scary sharp.

To be honest I've had mine (one plus a spare) for five years or more (about 15 quid in Boots, still available, I think), and they haven't needed sharpening so far. I clean/sterilise/degrease them regularly using surgical spirit, but otherwise use no lubricants or anything. I'll have a look with a hand lens to see what state the cutters are in...

My Philishave is over 15 years old & used every day. The motor just seems to keep on going.

All I do with mine is bung the complete head in with the washing up once a week, then split it into the component parts & give each a quick once over with an old toothbrush. I keep each cutter set in their respective pairs as I was once told by my brother-in-law who sold white goods & electricals, that they bedded themselves in & didn't like being mixed. Could be just an urban myth of course but it seems to have worked for me.

Thanks Eric & Robbo.
