Material Notes:
SK5 and SK51 are JIS-standard high-carbon tool steels with a carbon content of 0.75%–0.85%. They combine high hardness with good toughness. SK51 offers slightly better wear resistance and fatigue resistance for continuous high-load cutting. SK5 is more cost-effective for medium-intensity processing.
Key Product Advantages:
-
Long-lasting wear resistance: High-carbon tool steel extends blade life and reduces replacement downtime.
-
High cutting precision: Precision-ground edge produces smooth cuts and reduces secondary finishing.
-
High toughness, low breakage: Uniform heat treatment and flatness support high-speed continuous operation.
-
Multi-material compatibility: One blade type can handle leather, paper, carton, sponge, non-woven fabric, and more.
3. Why Choose Us: Advantages for the Bangladesh Market
3.1 Bangladesh Leather & Footwear Industry Is Growing Fast
Bangladesh is the world’s 8th largest footwear producer. Leather and footwear exports account for 1.54% of the country’s total exports and have grown at an average annual rate of 29.8% over the past five years. From July 2024 to May 2025, leather footwear exports increased by 28.96% year-on-year to US$620 million. Total leather and leather goods exports reached nearly US$1.039 billion.
This growth directly drives demand for cutting consumables. Band knife blades are high-frequency consumables used in shoe upper splitting, leather splitting, and shoe material cutting. They offer stable repeat purchase demand and short replacement cycles.

5. FAQ
Q1: What is the difference between SK5 and SK51 band knife blades?
A: Both are JIS-standard high-carbon tool steels. SK51 has slightly higher carbon content (0.75%–0.85%) and better wear resistance, making it suitable for high-load continuous cutting. SK5 is more cost-effective for medium-intensity processing. Both have a hardness range of HRC 47–51. Selection depends on cutting material and daily output.
Q2: How thick can this band knife cut?
A: Cutting thickness depends on the machine. The blade itself is 0.45 mm thick. With a band knife cutting machine, it can cut from 0.5 mm thin leather to 180 mm stacked materials (e.g., SG-BK900 cutting height: 180 mm).
Q3: What are the import duties for Bangladesh?
A: Under HS Code 82089000, the total effective tax burden in Bangladesh is approximately 28.73%, including 1% CD, 15% VAT, 5% AIT, and other charges. We provide full customs clearance documentation support.
Q4: Can you customize band knife dimensions?
A: Yes. Custom length: 2590–12630 mm; width: 3–50 mm; thickness: 0.45–1.5 mm. Edge types include straight, wavy, and toothed. OEM/ODM services are available.
Q5: What is the MOQ and lead time?
A: Standard items: MOQ 1 pc, lead time 7–15 days. Custom items: MOQ 50 pcs, lead time 15–25 days. Shipping by sea, air, or express. FOB Shenzhen / Foshan / Guangzhou.
Q6: How should I maintain the band knife to extend its life?
A: Sharpen the blade before first use. Store in a dry environment and keep the blade relaxed when not in use to prevent breakage. Regularly check tension and edge wear.
