Product Features

Stainless Block

Feature 01 Best balance of strength and
lightweight properties

Many of ASANO’ s blocks use stainless steel casting-integrated bodies.
The carefully crafted main bodies, e.g. ribs, are created in sections requiring strength, to which force is applied so that such sections develop strength, lightness, and compact
characteristics simultaneously.

Feature 02 Combination of casting and
forging suitable for required

ASANO has superior casting capabilities that enable shapes to be formed with a high degree of freedom.
Combining both casting and forging produces products that are compact and lightweight as well as strong, both of which are characteristics that are difficult to develop at the same time.

Feature 03 Design that prevents nets and ropes
from becoming entangled and damaged

Both ends of the sheave are fitted into the main body to eliminate the clearance between the sheave and main body. ASANO always pays extremly high attention to detail in this original design that does not damage tools, such as ropes and nets.

Feature 04 Smooth sheave rotation and captive pin

ASANO’ s blocks containing bearings have shield bearings to ensure
smooth rotation even after having been used for an extended period of time.
In addition, the end of the bolt are caulked so that it prevents bolts from
unexpectedly coming loose and sheaves from coming off.

Feature 05 Superior seawater resistance thanks
to special stainless steel

Realizing that many blocks are used in extreme environments, many block products are manufactured from special stainless steel.
This special stainless steel offers superior corrosion- and abrasion-resistant characteristics, and extends the product life which subsequently reduces costs.

Fishing Gear &
Ship Equipment

Feature 01 Adoption of special stainless
steel that meets fishing industry

ASANO’ s fishing gear uses special stainless steel with superior corrosion- and abrasion-resistance.
We analyze the characteristics of raw materials, such as hardness and tenacity, and manufacture products suitable for
locations and intended purposes of products based on our experience.

Feature 02 Well-thought out practicality
and functionality

Our products are derived from ASANO’ s monodzukuri(manufacturing) and are suitable for demanding professional work environments. For example , the Snap Hook with 1.3 tons working load limit is compact and fits snugly into hand, while its round shape is easy on ropes.

Feature 03 Strength and sophisticated form
achieved by our casting techniques

The strength of the 3-Way Roller has been enhanced by integrating the main body using casting.
Its curved body prevents ropes from becoming caught. ASANO’ s superior casting technology has been applied to create beautifully finished quality.

Feature 04 User oriented rapid product

Based on the valuable opinions obtained not only from users in Japan, but also from fishermen abroad, designing shapes suitable for various tasks is executed, and products are manufactured while confirming the shapes using 3D printed samples.

Feature 05 Pioneer of fishing industry products

ASANO started manufacturing stainless steel fishing gear and ship equipmentsin 1977.
Among many products, our legacy product, the Auto Shackle, was developed ahead of other companies over 20 years ago. Its functions proved innovetive and the product has received overwhelming support .
