Hi Sal,
nice hearing from you.
The new unpleasant part in the german weapon law about normal one hand knives is the following:
)(1) Es ist verboten[...]
3. Messer mit einhändig feststellbarer Klinge (Einhandmesser) oder feststehende Messer mit einer Klingenlänge über 12 cm zu führen.
(2) Absatz 1 gilt nicht
1. für die Verwendung bei Foto-, Film- oder Fernsehaufnahmen oder Theateraufführungen,
2. für den Transport in einem verschlossenen Behältnis,
3. für das Führen der Gegenstände nach Absatz 1 Nr. 2 und 3, sofern ein berechtigtes Interesse vorliegt. Weitergehende Regelungen bleiben unberührt.
(3) Ein berechtigtes Interesse nach Absatz 2 Nr. 3 liegt insbesondere vor, wenn das Führen der Gegenstände im Zusammenhang mit der Berufsausübung erfolgt, der Brauchtumspflege, dem Sport oder einem allgemein anerkannten Zweck dient.
(1) It is forbidden to carry knives with one-hand locking Blade (Onehandknife) oder fixed blades with a blade length over 12 cm.
(2) Part 1 does not apply for
1. use at foto-, film- or tv-shootings or theater
2. for transport in a locked case
3. carrying it if you have a "legal reason".
(3) a "legal reason" is particularly with regard to your job, traditional stuff, sport or a generally accepted purpose.
Fixed blades under 12cm blade length are definitely okay, two-hand-folders too.
Everything else is unclear.
For example, the UK penknife isn't a one-hand-locking blade, but it could be seen as a onehandknife, which is specifically mentioned as a word in the law. Since there are no specific instructions for the police yet or any explanations of the lawtext, nobody knows for sure.
It is even uncertain if the 12 cm blade length should only be applied to fixed blades. The text is written in a way that the 12 cm could also apply to one hand locking blades - even if that wasn't intended.
The first experiences with the police were not that nice - apparently collecting all onehandknifes is the least amount of trouble for them since they don't really know what to do.
The term "berechtigtes Interesse" (legal reason) is so vague that everything is possible. In Bavaria some government guy said every purpose except selfdefense is sufficient. But the police doesn't know that and can decide otherwise.
Please note that it only affects the carrying of the knives - onehand folders are still legal to own & to transport.
IANAL: A Spyderco that is totally "streetlegal" had to be a fixed blade under 12 cm blade length oder a folder that has nothing to do with onehand-whatsoever.
absolut legal = folder blade under 12cm
Dirk, 12cm is only interesting for fixed blades.
Legal is to carry:
[...]
one hand open folder with non locking blade as UK pen knife
We do not know that for sure. But the Danish pen knife should be no problem.
