China ★ Stainless Steel Diver's Knife BLACK ★ Spearfishing Freediving

This is a black, stainless steel diver's knife from an unknown Chinese brand.
It measures approximately 21cm in total length, with a blade length of about 9.8cm, a blade width of about 2.5cm, and a thickness of 3mm. The material is 440C, which is resistant to rust and comparable to SUS.
The case has a locking mechanism that allows for one-touch removal and a secure click when inserted.
The case and two straps are included.
The straps are made of a rubber-like material and do not appear to be very durable.
As it is a Chinese product, it is advisable not to expect high quality.

*Please Note*
Knives such as SALVIMAR's PREDATHOR and OMER's LASER have blades longer than 5.5cm and a sword-like shape (sharply pointed tip, double-edged, and symmetrical). These may violate the Firearms and Swords Control Law in Japan.
There are individuals who sell such knives with irresponsible explanations, claiming they are legal because one side has a serrated edge, or because they are sold at well-known stores. However, there is a high probability that they are illegal.
Given that freediving and spearfishing can easily be suspected of illegal fishing and reported, it is best to avoid carrying such knives.
Do not underestimate the seriousness of carrying such knives.
Possession of such illegal knives is equivalent to the illegal possession of actual firearms.
Violating the Firearms and Swords Control Law is a serious offense, and law-abiding citizens should absolutely not get involved.
Especially when buying or selling online, as records remain, it is extremely dangerous.
If even one purchaser uses it for criminal activity and it is discovered, an investigation may follow, and simply having it stored at home could lead to charges.

If you have already purchased one or are considering purchasing one, it is recommended to consult with the safety division of your local police station.
This product is a non-symmetrical knife that does not violate the Firearms and Swords Control Law. However, carrying it without a justifiable reason is prohibited by the Minor Offenses Act as it is a blade exceeding 6cm in length.
It is permissible to carry it for justifiable reasons such as during diving or camping, and during the travel to and from these activities. However, it must be stored appropriately.
