The Herman Knives SLIM #0449 is a direct-from-maker custom folding knife in mint condition. This refined Polish custom folder pairs a Bohler M398 powder stainless steel blade with a gray milled Grade 5 titanium handle, satin Grade 5 titanium backspacer, Grade 5 titanium pocket clip, and Herman’s improved custom ceramic bearing system.
The SLIM series focuses on elegance, compact carry, and everyday practicality. As a result, this knife works well for collectors who appreciate a dress-forward folder that still offers premium materials and serious mechanical engineering. It also includes the original Herman box, microfiber cloth, Pruciak Protector Glide for Herman oil, and the dedicated stainless steel screwdriver manufactured in-house by Herman Knives.
Herman Knives SLIM #0449 Direct From Maker
The Herman Knives SLIM #0449 brings a cleaner and more understated look than the more ornate Herman builds. However, it still delivers the precision, machining, action, and finish quality that collectors expect from Bartosz Herman’s shop.
The gray milled titanium handle gives the knife a subtle, versatile appearance. Meanwhile, the textured milling adds grip and depth without making the folder look overly tactical. Because the SLIM profile stays light and compact, it fits naturally into both formal and everyday carry settings.
This example measures 8.78 inches overall, with a 3.74-inch blade, 5.00-inch closed length, and 4.59-ounce weight. Therefore, it offers full-size function while keeping the thin, elegant feel that defines the SLIM model.
Bohler M398 Stonewash Blade
The blade uses Bohler M398 powder stainless steel with a stonewash finish. Herman heat treated the blade with deep cryogenic liquid nitrogen treatment, bringing the hardness to 62–63 HRC.
The blade measures 3.74 inches with a 0.126-inch blade thickness and 1.06-inch blade width. Its clip point profile gives the knife a clean, useful shape, while the stonewash finish helps hide light handling marks better than a high-polish blade.
Additionally, M398 gives the knife a premium steel identity that separates it from more common M390 or MagnaCut configurations. Collectors who follow Herman Knives often appreciate this type of steel and finish pairing because it balances cutting performance, corrosion resistance, and understated visual appeal.
Gray Milled Grade 5 Titanium Handle
The handle uses Grade 5 titanium with a gray milled finish. This gives the knife strength, low weight, and a clean modern look. In addition, the milling pattern adds texture across the handle while preserving the slim pocket profile.
Herman also fitted this knife with a satin Grade 5 titanium backspacer and a Grade 5 titanium pocket clip. Those details keep the build cohesive from every angle. The titanium liner lock adds strength, while the custom hardware gives the folder the refined Herman feel.
Because this SLIM avoids bright inlays or exotic color treatments, it has a quieter collector personality. However, that restraint makes the knife especially versatile for buyers who prefer premium craftsmanship without a loud finish package.
Improved Herman Ceramic Bearing System
Herman Knives equips this SLIM with a custom-made ceramic caged bearing system. The improved bearing design uses 16 ceramic balls and helps keep the action smooth, stable, and consistent.
The washer system also deserves attention. Herman makes the washers from M390 powder metallurgy steel, heat treats them to 60 HRC, cuts them with EDM precision, and hand laps them up to a 4000-grit finish. The washers measure approximately 0.199 inches inside diameter, 0.471 inches outside diameter, and 0.024 inches thick.
Furthermore, the improved pivot system uses a phosphor bronze bushing, a seven-petal clover-style screw, and a Torx T20 adjustment interface. This setup reduces unwanted play and supports clean blade rotation. It also keeps the knife serviceable with the included Herman screwdriver.
Mint Condition With Original Box and Accessories
This Herman SLIM #0449 comes in mint condition and includes the original box and accessories listed with the knife. The set includes the Herman box, microfiber cloth, Pruciak Protector Glide for Herman oil, and dedicated stainless steel screwdriver.
These accessories matter because Herman produces the screwdriver specifically for their pivot system. Therefore, the next collector receives both the knife and the proper tool for safe, accurate adjustment.
