My time is up with the Slim and the Superspeed.
Used both razors with a Polsilver, a Lab Blue and a 7 O'Clock Yellow, and all with Castle Forbes Limes shaving cream.
Firstly the Slim: It seemed to like the 7 O'clock best, but gave a satisfactory, if unexciting, shave with all three blades. I used it set at 7 and considered it a nice everyday shaver, quite mild even at 7.
The Flairtip: What a great little razor. Felt smooth and mild but gave an exceedingly close shave with all three blades. A great choice for anyone looking for a reliable go-to razor that chopped down my steel wool whiskers in double quick time.
Thank you John for the opportunity to try these razors out, much appreciated. Spitfire is next in line if you PM me your contact details.
I would encourage everyone to have a go at these excellent instuments.
