Side wiper to remove lather, not used for the Krona. Adjustment mechanism using TTO knob, not used for the Krona.
TTO knob design to reduce variability of clamping force. Bottom-dial adjuster, not used for the Krona. However, it is not a T.T.O (twist-to-open) as its knob needs to be pulled to close the doors and then set on the intermediate "Rinse" position, as described in the patent, to keep them closed. 1966 design described above: a longer knob than the original design, but the same two-ply center bar. The known example is about the same height and weight as an early non-adjustable Krona: approximately 105-mm and 57-g. At least one example of this razor exists, but it may have been a prototype or from a very limited production run. Schick also held patents showing an adjustable razor visually similar to the Krona. US3378921, filed, issued, covering the Krona center bar and stem designs.US3377701, filed, issued, covering the Krona knob design.US3376637, filed, issued, covering the Krona center bar design.This NOS packaging also included patent information: D80.Īt least one NOS package has been found with bar codes, so the Krona was still in production ca. This includes the special bicentennial " Executive Travel Case" sets, which were first marketed in 1965. 1968-76 or later: plastic knob, one-ply center bar, various codes, doors stamped "Schick - Schick" or "Schick - Krona" or "Schick - (blank)", approximate weight 38-g.Īll known gold Kronas were of the 1964-65 style. When the Schick/Eversharp/Krona DE was advertising, it was a vehicle for DE blade sales.
Schick might have started use of the Krona name in 1959 - maybe only internally or in test markets - but in 1960 it was only used for injector blades.
#SCHICK BLADES KRONA EDGE CODE#
1967-68: design revised for 1967 patents, plastic knob, one-ply center bar, often labelled with code 1-M, "PATENTS PENDING", doors stamped "Schick - Schick" or "Schick - Krona" or "Schick - (blank)", approximate weight 38-g. For the start date, I found contemporary sources discussing the introduction of Schick DE razors in 1963. 1966: as above, but grey instead of black and branded EVERSHARP with eagle logo.
#SCHICK BLADES KRONA EDGE PLUS#
1966: design revised with long metal knob, two-ply center bar, often labelled with code 6-M, "3-2" or "4-2", and "Made in U.S.A" plus either a "SCHICK" or a triangle logo, blank doors, approximate weight 50-g. 1964-65: original design with short metal knob, two-ply center bar, labelled with code M-5 and "Made in U.S.A" plus either a "SCHICK" or a triangle logo, blank doors, approximate weight 55-g. One way to look at the available evidence is: The order differs: some razors have "M-5" and others "6-M". All known examples have an "M", which may indicate the Schick plant in Milford or may have some other meaning. Most razors feature various alphanumeric codes, but their meaning is not understood and probably does not correlate to production dates. The design revision was probably intended to reduce manufacturing costs, making "free razor" offers more economical. These appear to refer to the 1967 patents, so would have been made 1967-68. Razors have been reported with "PATENTS PENDING" marks. 1967 production adopted a patented single-ply center bar (see below for patents see gallery for photo). 1967 the center bar and TTO mechanism was based on Gillette designs: the "two-ply" version. Illustrations featured both black and metallic knobs. By October 1968 the razor was being advertised as a giveaway with Schick Krona-Chrome blades. Razors with instructions dated as early as 1964 have been reported, but the earliest known illustrations appeared in April 1966. It was also sold as a Schick Double Edge and an Eversharp, and in Japan as the Schick D-80. Metal parts were finished in nickel or gold.
The TTO doors were sometimes plain, or embossed with "Schick/Schick" "Schick/Krona", or "Schick/(blank)". The TTO knob was either metal or black plastic. All featured metal construction with a resin-coated handle, in black except for the Eversharp which was grey. I have and continue to learn so much.and now I enjoy shaving rather than hate it.There were several minor variations of this razor. Any suggestions would be considered and appreciated. Thinking of feeding the emerging RAD with the purchase of something more aggressive, as both the Tech and the Krona are almost overly mild. Love my Tech.but I think I love the Krona more. I really like the longer handle for control, and the weight on the head compared to the long tapered handle just really feels more comfortable in my hand. The biggest advantage I think the Krona has over the ball-end Tech is balance. I thought I would not enjoy the black plastic type handle, but it is heavier and more rugged than I thought it would feel.very grippy. I also enjoy the butterfly convenience (first one.need to try a SuperSpeed!). Now I have clearly come down with a bought of RAD, because I just picked up a Schick Krona and gave it a run today. Very tactile, and a close enough shave for me with Wilkinson blades. I quickly stepped up to a pre-war ball end Tech. I originally bought a cheap Wilkinson Sword classic to get rolling.
