Steel Profiles vs EdgeSage

Steel Profiles is the steel section reference for structural engineers, fabricators, detailers and contractors. Look up nearly 10,000 sections from six international standards, check them to Eurocode 3 or AISC 360, and keep your take-offs in sync across iPhone, iPad and Mac. NEW IN 6.0 - Design checks to EN 1993-1-1 and AISC 360-22: classification, axial force, bending, shear, flexural and lateral-torsional buckling, beam-column interaction, with every formula shown - Section Builder: welded I and box sections, built-up channels, tees and angles, plated beams, with full properties - Bolts: metric M8 to M64 and imperial 1/2" to 1 1/2", with shear, tension, bearing and slip resistance - Steel grades: EN 10025, EN 10210/10219, ASTM, CSA, AS/NZS and JIS, with strengths by thickness - iCloud sync of favorites, projects and saved sections - Bulb flats (HP) to EN 10067 - PDF and CSV export, imperial fractions and smarter search (HEA 200, HEA200, W10x49) SECTION PROPERTIES - Complete geometric and structural properties with descriptions and a cross-section drawing - Filters by area, weight, moment of inertia, section moduli and radii of gyration - Favorites, Spotlight search and Siri TOOLS - Equivalent Finder: the closest section in another standard, optionally from the same shape family - Comparator: up to three sections side by side - Weight lists organized in projects and folders, exported to CSV - Unit converter for engineering units LIBRARIES USA: AISC 16 and AISC 16 SI (16th Edition), AISC 14 and AISC 14 SI (14th Edition) Canada: CISC 92 Europe: IPE, HE (HEA, HEB, HEM, HEAA), HD, HL, HP, IPN, UPE, UPN, angles, tees, bulb flats, hot-finished and cold-formed hollow sections United Kingdom: UB, UC, UBP, J, PFC, T, angles, hollow sections Australia / New Zealand: AS/NZS FREE AND PAID The free download includes dimensions for every library, the weight calculator, Section Builder, bolts, steel grades, the unit converter and iCloud sync. Unlock a library to see its full properties and run design checks on its sections, or get All Libraries for everything. Results are design aids for preliminary sizing and must be verified by a qualified engineer.

EdgeSage is a knife-steel reference and sharpening coach that works entirely offline. KNOW YOUR STEEL Search 52 knife steels by name, alias or maker. Open any steel for its composition, its heat-treat notes, and plain-language pros and cons. Put two steels side by side and compare them across five axes — edge retention, toughness, corrosion resistance, wear resistance and ease of sharpening — on radar and bar charts. NOT SURE WHICH STEEL? Answer four questions about how you actually use a knife and the Steel Wizard returns a ranked shortlist, each result one tap from its sharpening recipe. A RECIPE, NOT A GUESS Every steel resolves to a concrete plan: the target angle in degrees per side, a grit ladder with micron equivalents, what to look for before moving to the next stone, a strop step, and a realistic time estimate. Recipes account for the abrasive a steel actually needs — vanadium-carbide steels are flagged for diamond. HOLD YOUR ANGLE Rest your iPhone on the blade and the coach reads your bevel angle live from the device's motion sensors, in degrees per side. It taps when you drift and speaks a correction, holds an on-target streak while you stay in the band, and counts strokes and time. Calibrate against your stone first so the reading is relative to the surface you're working on. BUILT FOR YOUR SETUP Freehand stones, Wicked Edge, KME Precision, Lansky, Work Sharp Precision Adjust and strops. Wicked Edge, KME and Lansky include a setup calculator that estimates the real edge angle for your blade height, so you can pick the right mark or slot. YOUR KNIVES, YOUR HISTORY Keep your knives with their steel, a photo, an angle override and their full sharpening history, including a sharpness trend so you can see how an edge is actually holding up. NO ACCOUNT NEEDED The steel database, the Wizard, the recipes and the angle coach all work from first launch with no connection and no account, and your knives, sessions and photos are stored on your device. Sign in only if you want more: your library syncs across your devices, you can add anonymous field reports to the community Steel Leaderboard, and EdgeSage AI chat, photo steel ID and custom recipes unlock. EDGESAGE PRO The free app is complete: the full steel database, the Wizard, every recipe, the angle coach and session logging are all free and stay free. Pro lifts the limits in the free tier: • Unlimited knives (free keeps 3) • A third column in the comparator (free compares 2) • A higher daily limit on EdgeSage AI chat and photo steel ID • Saved chats — keep every answered EdgeSage AI conversation on this iPhone, search them, pick them back up, share as text or PDF Pro is $4.99/month or $39.99/year.
